TLV320ADC3001 描述
The TLV320ADC3001 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.
