The TLV320ADC3001 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 I2C, enabling mono or
stereo recording. Low power consumption makes the TLV320ADC3001 ideal for battery-powered portable
equipment.
The AGC programs to a wide range of attack (7 ms–1.4 s) and decay (50 ms–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
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.
