TLV320ADC3101集成电路（IC）的ADC/DAC-特殊用途规格书PDF中文资料

TLV320ADC3101属于集成电路（IC）的ADC/DAC-特殊用途。由德州仪器制造生产的TLV320ADC3101ADC/DAC - 特殊用途该产品族中的产品可用于模拟和数字表示的信息转换，适用于特定用例，或集成了通用数据转换器中不常见的其他功能。例如针对超声或汽车雷达应用集成了低噪声放大器和可变增益级的器件、注重音频和视频的产品、在段码式显示器上集成显示测量值功能的器件、集成输入输出电气隔离的器件等。

描述 Description

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 batterypowered

portable equipment.
