ams AS8510 Data Acquisition Front-End IC is a virtually offset free, low noise, two channel measurement device. AS8510 is tailored to accurately measure battery current from mA range up to kA range in conjunction with a 100μΩ shunt resistor in series with the battery rail. Through the second measurement channel it enables capture of, either battery voltage synchronous with the current measurement, or, measure the analog output of an internal or external temperature sensor. Both channels are matched and can either measure small signals up to ±160mV versus ground, through programmable gain amplifier or larger signals in the 0 to 1V range without the amplifier.
ams AS8510 Copper Shunt Reference Design provides a blueprint to achieve linear current measurement up to 100A with an accuracy of ±1% by monitoring voltage drop across a PCB's copper track. The reference design takes advantage of the very high sensitivity and precision of the AS8510, an integrated data acquisition front end which provides two measurement channels. By using a new technique involving the ams AS8510 data-acquisition front end, designers of Battery Management Systems (BMS) can eliminate the precision shunt resistor normally used in current-sensing applications. The ams AS8510 Copper Shunt Reference Design is intended for a current range of ~40A operation and 60A maximum.

ams AS5161 Rotary Position Sensor is a contactless Hall-based magnetic position sensor for very accurate angular measurement over a full turn of 360°. A sub range can be programmed to achieve the best output characteristic for the application. A simple diametrical 2-pole magnet rotating on the center of the IC is required: the magnet may be placed above or below the IC. The AS5161 is a compact integrated solution which provides the absolute angle measurement with a resolution of 0.09° over a full revolution as PWM output signal. The internal 14-bit core of the AS5161 enables a fine programming of the start and stop positions with a resolution of 0.02° to allow the finest system mechanical adjustments. High level of flexibility is guaranteed by the programmability through the UART interface shared with the output pin, to reduce the number of pins in the application. The angular output data can be linearized in the final production to further increase the precision of the measurement. With embedded overvoltage protection and reverse battery protection the AS5161 can fulfill the most demanding automotive safety standard.

The TCS3472 family of devices provides a digital return of red, green, blue (RGB), and white light sensing values. An IR blocking filter, integrated on-chip and localized to the color sensing photodiodes, minimizes the IR spectral component of the incoming light and allows color measurements to be made accurately. The high sensitivity, wide dynamic range, and IR blocking filter make the TCS3472 an ideal color sensor solution for use under varying lighting conditions and through attenuating materials. The TCS3472 color sensor has a wide range of applications including RGB LED backlight control, solid-state lighting, health/fitness products, industrial process controls and medical diagnostic equipment. In addition, the IR blocking filter enables the TCS3472 to perform ambient light sensing (ALS). Ambient light sensing is widely used in display-based products such as cell phones, notebooks, and TVs to sense the lighting environment andenable automatic display brightness for optimal viewing and power savings. The TCS3472, itself, can enter a lower-power wait state between light sensing measurements to further reduce the average power consumption.

ams AS3953 NFC Interface IC (NFiC) delivers low cost, ultra low power NFC forum functionality to multiple different applications. The AS3953 is a analog front-end with integrated 14443A data framing and SPI interface. It is designed to create a fast data link between an ISO 14443A reader device (PCD) and a microcontroller. The AS3953 is passively powered meaning that it can be supplied from the PCD magnetic field, eliminating the need of a continual external supply. This makes the AS3953 perfect for wireless communication to a low-power battery powered device. The AS3953 is used with an appropriate antenna coil connected to the terminals LC1 and LC2, and behaves as a normal passive ISO 144443A tag (PICC). After the anti-collision protocol is passed, the PCD sends a Wake-up command, which wakes up the microcontroller by sending an interrupt. From this point onwards, the AS3953 serves as a data link between the microcontroller and the PCD. AS3953 can also operate as NFCIP-1 target at 106 kb/s.
ams AS5145 12-Bit Programmable Magnetic Rotary Encoder is a contact less magnetic rotary encoder for accurate angular measurement over a full turn of 360 degrees. It is a system-on-chip, combining integrated Hall elements, analog front end and digital signal processing in a single device. To measure the angle, only a simple two-pole magnet, rotating over the center of the chip, is required. The magnet can be placed above or below the IC. The absolute angle measurement provides instant indication of the magnet's angular position with a resolution of 0.0879º = 4096 positions per revolution. This digital data is available as a serial bit stream and as a PWM signal. An internal voltage regulator allows the AS5145 to operate at either 3.3V or 5V supplies.
ams AS5048 Magnetic Rotary Encoders are an easy to use 360° angle position sensor with a 14-bit high resolution output. The maximum system accuracy is 0.05° assuming linearization and averaging is done by the external microcontroller. The IC measures the absolute position of the magnet’s rotation angle and consists of Hall sensors, analog digital converter and digital signal processing. The zero position can be programmed via SPI or I²C command, therefore no programmer is needed anymore. This simplifies the assembly of the complete system because the zero position of the magnet does not need to be mechanically aligned which helps developers to shorten their developing time. The sensor tolerates misalignment, air gap variations, temperature variations and as well external magnetic fields. This robustness and the wide temperature range (-40°C up to +150°C) of the AS5048 makes the IC ideal for rotation angle sensing in harsh industrial and medical environments. Several AS5048 ICs can be connected in daisy chain for serial data read out. The absolute position information of the magnet is directly accessible over a PWM output and can be read out over a standard SPI or a high speed I²C interface. AS5048A has a SPI interface, AS5048B I2C interface and both devices offer a PWM output. An internal voltage regulator allows the AS5048 to operate at either 3.3V or 5V supplies.
ams AS1345 high efficiency DC-DC step-up converter contains an internal
N-channel and an internal P-channel output isolation switch. ams AS1345
operates from a 2.9V to 5.0V supply and can boost voltages up to 18V. A
hysteretic control scheme is used to provide the highest operating
efficiency over a wide range of input and output load conditions. The
internal MOSFET switches reduce the external component count and a high
switching frequency allows the use of tiny surface mount components. The
AS1345 employ a factory set current limit to reduce ripple and external
component size in low output current applications. With a 500mA current
limit the AS1345 is capable of providing 20mA @ 18V output.

The wide input voltage range, low-dropout voltage, and high-accuracy output voltage makes the AS1360 perfectly suited for 2- and 3-cell battery-powered and portable applications. The low dropout voltage (650mV) prolongs battery life and allows high current in small applications when operated with minimum input-to-output voltage differentials. The device features very stable output voltage (using only 1µF tantalum or aluminum-electrolytic capacitors), strict output voltage regulation tolerances (±0.5%), and excellent line-regulation. The AS1360 is available in a 3-pin SOT23 package.
