The TLV320ADC3101 is a low power, stereo audio Analog to Digital Converter (ADC) supporting sampling rates from 8 kHz to 96 kHz with an integrated programmable gain amplifier providing up to 40dB analog gain or AGC. Front-end input coarse attenuation of 0dB, 6dB, or off, is also provided. The inputs are programmable in a combination of single-ended or fully differential configurations. Extensive register-based power control is available via I2C, enabling mono or stereo recording. Low power consumption makes the TLV320ADC3101 ideal for battery-powered portable equipment. The AGC programs to a wide range of attack (7ms 1.4s) and decay (50ms 22.4s) times. A programmable noise gate function is included to avoid noise pumping. Low-latency IIR filters optimized for voice and telephony are available, as well as linear-phase FIR filters optimized for audio. Programmable IIR filters are also available and may be used for sound equalization, or to remove noise components. The audio serial bus can be programmed
