Product Overview
The TLV320AIC20CPFBR is a high-performance, low-power stereo audio codec from Texas Instruments, designed for portable and embedded audio applications. It features two analog-to-digital converters (ADCs) and two digital-to-analog converters (DACs) with support for sampling rates up to 96 kHz. The device integrates a programmable gain amplifier (PGA), microphone bias, and headphone driver, making it ideal for voice and music processing. Housed in a compact 48-pin TQFP package (7x7 mm), it offers a flexible serial audio interface (I2S, left-justified, right-justified, DSP) and control via I2C or SPI.
