miniDSP built-in low power stereo ADC 'TLV320ADC3101'
Equipped with a programmable gain amplifier that provides up to 40dB of analog gain or automatic gain control (AGC), supporting sampling rates from 8kHz to 96kHz. It features a programmable miniDSP for custom audio processing. The front-end input attenuation can be set to 0dB, -6dB, or off. Inputs can be programmed in a combination of single-ended or fully differential configurations. Extensive register-based power control via I2C interface enables mono or stereo recording. It has low power consumption, making it ideal for battery-operated portable devices. The AGC can be programmed for a wide range of attack times (7ms to 1.4s) and decay times (50ms to 22.4s). To prevent noise pumping, it includes a programmable noise gate function. It also features low-latency IIR filters optimized for voice and telecommunication, linear phase FIR filters optimized for audio, and programmable IIR filters that can be used for sound equalization and noise component removal. Evaluation modules and reference designs are also available.
