Cirrus Logic CS1615/CS1615A/CS1616/CS1616A LED Drivers monitor and adapt to the dimmer type in use and select the appropriate operating mode. Primary side constant current control enables LED current regulation with less than ±5% and is configurable for isolated and non-isolated topologies.

Cirrus Logic CS42516 192 kHz 6-Channel Codec

Cirrus Logic's CS42516 192 kHz 6-Channel Codec provides two analog-to-digital and six digital-to-analog delta-sigma converters, as well as an integrated S/PDIF receiver. The CS42516 integrated S/PDIF receiver supports up to eight inputs, clock recovery circuitry and format auto-detection. The internal stereo ADC is capable of independent channel gain control for single-ended or differential analog inputs. All six channels of DAC provide digital volume control and differential analog outputs. The general-purpose outputs may be driven high or low, or mapped to a variety of DAC mute controls or ADC overflow indicators. The CS42516 is ideal for audio systems requiring wide dynamic range, negligible distortion and low noise, such as A/V receivers, DVD receivers, digital speaker and automotive audio systems.

Cirrus Logic CS4207 Low Power HD Audio Codec

Cirrus Logic's CS4207 Low Power HD Audio Codec is a highly integrated multi-channel low-power HD Audio Codec featuring 192 kHz DACs, 96 kHz ADCs, 192 kHz S/PDIF Transmitters and Receiver, Microphone pre-amp and bias voltage, and a ground centered Headphone driver. Based on multi-bit, delta-sigma modulation, it allows infinite sample rate adjustment between 32 kHz and 192 kHz. In addition to its many features, the CS4207 operates from a low-voltage analog and digital core, making this part ideal for portable systems that require low power consumption in a minimal amount of space.

Cirrus Logic CS6422 Full-Duplex Speakerphone IC

Cirrus Logic's CS6422 Full-Duplex Speakerphone IC is an enhanced speakerphone IC that enables full-duplex conversation using echo cancellation and suppression in a single-chip solution. The CS6422 can easily replace existing half-duplex speakerphone ICs with a huge increase in conversation quality. The CS6422 consists of telephone & audio interfaces, two codecs and an echo-cancelling DSP. Most modern speakerphones use half-duplex operation, which alternates transmission between the far-end talker and the speakerphone user. This is done to ensure stability because the acoustic coupling between the speaker and microphone is much higher in speakerphones than in handsets where the coupling is mechanically suppressed.

Cirrus Logic CS1630 / CS1631 TruDim™ Digital LED Controllers

Cirrus Logic CS1630 and CS1631 digital LED controllers are high-performance offline AC/DC drivers for dimmable and high color rendering index (CRI) LED replacement lamps and luminaires. CS1630 and CS1631 feature Cirrus Logic's TruDim™ proprietary digital dimmer compatibility control technology and digital correlated color temperature (CCT) control system that enables two-channel LED color mixing. CS1630 LED driver is designed for 120VAC line voltage applications, while the CS1631 is optimized for 230VAC line voltage applications. These Cirrus Logic devices offer up to 30 percent higher lumens per watt compared to single-channel drivers while providing improved color temperature quality. The devices provide near-100-percent TRIAC dimmer compatibility.

Cirrus Logic Energy Measurement ICs

Cirrus Logic Energy Measurement ICs are a high-accuracy energy measurement analog front end. These Energy Measurement ICs incorporate independent 4th order Delta-Sigma analog-to-digital converters for every channel, reference circuitry, and the proven EXL signal processing core to provide active, reactive and apparent energy measurement. RMS and power factor calculations for these Energy Measurement ICs are available and are output via a configurable energy pulse, or direct SPI/UART serial access to on-chip registers. Cirrus Logic Energy Measurement ICs also provide instantaneous current, voltage and power measurements that are available over the serial port.

The Cirrus Logic CS5505 is a Very Low Power 16-bit CMOS Analog-to-Digital (A/D) Converter which is ideal for measuring low-frequency signals representing physical, chemical and biological processes. This Cirrus Logic A/D Converter includes on-chip self-calibration circuitry which can be initiated at any time or temperature to ensure minimum offset and full-scale errors. The CS5505 serial port offers two general-purpose modes for the direct interface to shift registers or synchronous serial ports of industry-standard microcontrollers.

Cirrus Logic Power Monitor Reference Design

Cirrus Logic's CRD5463PM is a reference design and software that demonstrates the CD5463 power measurement IC. This Power Monitor Reference Design includes an integrated AC-DC power supply, voltage and current sensors, and isolated UART/USB interface. Working with the GUI software, this Cirrus Logic CRD5463PM provides accurate real-time measurements of line voltage, load current, line frequency, active power, reactive power, apparent power, power factor and temperature.

Cirrus Logic CS1501 / CS1601 Digital PFC Controllers

The Cirrus Logic CS1501 / CS1601 family of digital PFC controllers feature superior efficiency and THD (total harmonic distortion) performance across variable load conditions and enable smaller, simpler designs through a reduction in boost inductor size along with fewer required external components. These high-performance, active digital PFC controllers are Variable Frequency Discontinuous Mode (VF-DCM) ICs featuring Cirrus Logic's EXL Core® Technology that enables intelligent and adaptive switching that traditional analog PFC devices lack. The CS1501 / CS1601 operate at switching speeds up to 70kHz and the CS1601H operates up to 100kHz. These next generation controllers feature Current Sense (CS) and Zero Crossing Detect (ZCD) functionality, which enables accurate over-current protection, high overall efficiency, and best-in-class THD. The CS1501 / CS1601 / CS1601H are targeted for use in switch-mode power supplies (SMPS) applications, including LED / Fluorescent Lighting, DTVs, Servers / Telecom, Notebooks, and Desktops under 300W.
