The TLV320ADC3101 device 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 40-dB analog gain or AGC. A programmable miniDSP is provided for custom audio
processing. Front-end input coarse attenuation of 0 dB, –6 dB, 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 an I2C interface, 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 (7 ms to 1.4 s) and decay (50 ms to 22.4 s)
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 to support
I2S, left-justified, right-justified, DSP, PCM, and TDM modes. The audio
bus may be operated in either master or slave mode.
A programmable integrated PLL is included for flexible clock generation and provides
support for all standard audio rates from a wide range of available MCLKs, varying from 512 kHz to
50 MHz, including the most popular cases of 12-MHz, 13-MHz, 16-MHz, 19.2-MHz, and 19.68-MHz system
clocks.
