概述

Description

TLV320AIC26IRHBR is TI’s low‑power stereo audio CODEC with integrated ADC/DAC and headphone driver. It is designed for portable/embedded audio applications.
Key points
- 2-channel 24‑bit ADC and DAC with analog mic bias, mic preamp, and line‑in
- Built‑in headphone/speaker driver for direct audio out
- Flexible digital interface: I2S, left‑justified, right‑justified, or DSP modes
- Control via I2C with a programmable register map; supports features like gain control, mute, de-emphasis, and power-down
- Low power, suitable for battery‑powered devices; operates from a single supply (see datasheet for exact ranges)
IRHBR suffix denotes a specific TI package/temperature variant; check the datasheet for exact pinout, voltage/thermal specs, and packaging details.
Common applications include mobile handsets, handheld recorders, audio accessories, VoIP devices, and embedded audio systems. For precise specs and register map, refer to the TLV320AIC26IRHBR datasheet and evaluation guide.

Features

Key features of TLV320AIC26IRHBR:
- Stereo 2-channel ADC and 2-channel DAC, 24-bit audio path
- Sampling rates up to 96 kHz (with common rates supported)
- Analog front end: mic input with bias, line-in, and headphone output
- Digital audio interface: I2S and left-justified formats; configurable master/slave
- I2C control interface for full register-programmable control (gain, routing, power modes)
- DSP-like features: programmable gain/volume, soft mute, de-emphasis, bass boost
- Low-power, single-supply operation with power-down modes
- Compact package (IRHBR) suitable for portable/embedded audio apps
Ideal for portable devices requiring integrated analog/digital audio, I2C control, and flexible I/O.

Package

HTSSOP-28 (28-pin) package. It’s RoHS-compliant/lead-free and typically shipped in Tape‑and‑Reel (BR) packaging.

Pinout

28-pin package (HTSSOP RoHS lead-free). It is a stereo audio CODEC with integrated ADCs/DACs (two channels), analog inputs (mic/line), headphone output, and a digital audio interface (I2S/PCM) for data transfer.

Manufacturer

- Manufacturer: Texas Instruments (TI).
