Maxim's MAX98356 PDM Input Audio Amplifier is a digital pulse-density modulated (PDM) input Class D power amplifier that provides Class AB audio performance with Class D efficiency. The MAX98356 Audio Power Amplifier from Maxim takes a stereo pulse density modulated (SPDM) input signal directly into the DAC and can be configured to produce a left channel, right channel, or (left + right)/2 output from the stereo input data. This IC features an extremely robust digital audio interface with very high wideband jitter tolerance (12ns typ) on PDM_CLK. The MAX98356 offers five selectable gain settings (3dB, 6dB, 9dB, 12dB, and 15dB) set by a single gain-select input (GAIN) and is available in a 9-pin WLP package (1.345mmx1.435mmx0.64mm). Other MAX98356 features include 2.5V to 5.5V single supply voltage operation, 3.2W output power into 4Ω at 5V, and operating temperature range -40ºC to +85ºC. The MAX98356 Evaluation Kit is a fully assembled and tested PCB that evaluates the MAX98356 PDM digital input Class D power amplifier. The MAX98356 Evaluation Kit operates from a single 2.5V to 5.5V power supply and is capable of delivering 3.2W into a 4Ω load with either filterless Class D outputs or with an optional Class D filter that eases evaluation.
Maxim Integrated MAX492 Dual Micropower Op Amps combine excellent DC accuracy with rail-to-rail operation at the input and output. The common-mode voltage extends from VCC to VEE, allowing these Maxim Integrated op amps to operate from either a single supply (+2.7V to +6V) or split supplies (±1.35V to ±3V). The MAX492 op amp requires less than 150μA supply current and are capable of driving a 1kΩ load. The input referred voltage noise is only 25nV/√Hz, and these op amps can drive loads in excess of 1nF. The precision performance of the MAX492 combined with its wide input and output dynamic range, low-voltage single-supply operation, and very low supply current, makes it an ideal choice for battery-operated equipment and other low-voltage applications.
Maxim Integrated MAX4477 Wide-Band, Low-Noise, Low-Distortion Op Amps offer rail-to-rail outputs and single-supply operation down to 2.7V. These Maxim Integrated op amps draw 2.2mA of quiescent supply current per amplifier while featuring ultra-low distortion, low input voltage-noise density, and low input current-noise density. The MAX4477 is unity-gain stable, with a gain-bandwidth product of 10MHz. These Maxim Integrated Wide-Band Op Amps are ideal for ADC buffers, DAC output amplifiers, low-noise microphone/preamplifiers, digital scales, and more.
Maxim Integrated MAX4252 Low-Noise, Low-Distortion Op Amps offer rail-to-rail outputs and single-supply operation down to 2.4V. Maxim Integrated MAX4252 op amps draw 400µA of quiescent supply current per amplifier while featuring ultra-low distortion (0.0002% THD), low input voltage-noise density (7.9nV/√Hz), and low input current-noise density (0.5fA/√Hz). These features make Maxim Integrated MAX4252 Low-Distortion Op Amps ideal for portable/battery-powered applications that demand low distortion and low noise.
Maxim Integrated MAX4238 Ultra-High Precision Amplifiers offer near-zero DC offset and drift through the use of patented autocorrelating zeroing techniques. This method constantly measures and compensates the input offset, eliminating drift over time and temperature and the effect of 1/f noise. Maxim Integrated MAX4238 precision amplifiers feature rail-to-rail outputs, operate from a single 2.7V to 5.5V suppler, and consume only 600µA, and an active-low shutdown mode decreases supply current to 0.1µA. The MAX4238 is unity-gain stable with gain-bandwidth product of 1MHz. These Maxim Integrated amplifiers are optimized for thermocouples, strain gauges, electronic scales, medical instrumentation, and instrumentation amplifiers.
Maxim Integrated MAX4163 Micropower Op Amps combine an exceptional bandwidth to power consumption ratio with true rail-to-rail inputs and outputs. MAX4163 op amps consume a mere 25µA quiescent current per amplifier, achieve 200kHz gain-bandwidth product, and are unity-gain stable while driving any capacitive load. The Maxim Integrated MAX4163 operates from either a single supply (2.5V to 10V) or dual supplies (±1.25V to ±5V), with an input common-mode voltage range extending 250mV beyond either supply rail. These Maxim Integrated devices use a proprietary architecture to achieve a very high input common-mode rejection ratio without the midswing nonlinearities present in other rail-to-rail op amps. This architecture also maintains high open-loop gain and output swing, while driving substantial loads. MAX4163 Micropower Op Amps are ideal for use in a variety of applications, including battery-powered devices, medical instruments, pH probes, portable equipment, cell phones, and more.
