3 Description
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.
