TLV320ADC3101

A 92dB signal-to-noise ratio low-power stereo analog-to-digital converter supporting digital microphones and miniDSP

Explanation   This TLV320ADC3101 is a low-power, stereo-to-audio analog-to-digital converter (ADC) that supports an 8 kHz sampling rate and features an integrated programmable gain amplifier that can provide up to 40 dB analog gain or AGC up to 96 kHz. A programmable miniDSP provides customized audio processing. Front-end input is 0 dB, -6 dB, or off, and coarse attenuation is also provided. The input is a combination of single-ended or fully differential configurations. Extensive register-based power control can be recorded via a single I2C interface, enabling mono or stereo. Low power consumption, making battery-powered portable devices TLV320ADC3101 the ideal choice. AGC schemes have a wide range of attacks (7 ms - 1.4 s) and attenuation (50 MS - 22 seconds).   Characteristics   Stereo audio ADC A signal-to-noise ratio of 92 decibels Supports ADC sampling rates from 8 kHz to 96 kHz Instruction-programmable embedded miniDSP Flexible programmable digital filtering with RAM coefficient, indication, and built-in processing module Low-latency IIR filter for speech Linear phase FIR filter audio Additional emotional intelligence, noise cancellation, or programmable IIR filters Digital filter coefficient up to 128 for programmable ADCs 6.
