Overview
The TLV320AIC32IRHBT, produced by Texas Instruments, is a highly flexible and low-power stereo audio codec. It is designed for use in portable, battery-powered audio and telephony applications such as smartphones, PDAs, and portable computing and entertainment devices. This codec integrates a stereo headphone amplifier, multiple inputs and outputs, and extensive power control features to minimize power consumption and reduce board space.
The device supports a wide range of sampling rates from 8 kHz to 96 kHz and includes programmable digital filtering for various audio effects. It operates from multiple power supplies: an analog supply of 2.7 V to 3.6 V, a digital core supply of 1.65 V to 1.95 V, and a digital I/O supply of 1.1 V to 3.6 V. The TLV320AIC32IRHBT is available in a compact 5 × 5 mm, 32-lead QFN package.
