TLV320AIC23BGQER

Codecs Overview

The TLV320AIC23BGQER is a high-performance stereo audio codec from Texas Instruments, utilizing multibit sigma-delta technology for its analog-to-digital and digital-to-analog converters. It supports sampling rates from 8 kHz to 96 kHz with data word lengths of 16, 20, 24, or 32 bits. The device features an ADC signal-to-noise ratio of up to 90 dBA and a DAC signal-to-noise ratio of up to 100 dBA at 48 kHz. It operates with a core digital supply voltage range of 1.42 V to 3.6 V and an analog/buffer supply range of 2.7 V to 3.6 V. The component is housed in a 32-pin MicroStar Junior package and is rated for commercial operating temperatures between -10°C and 70°C.
