Description
TLV320AIC26IRHBR is a low‑power TI stereo audio CODEC that combines two analog-to-digital converters (2x ADC), two digital-to-analog converters (2x DAC), and a headphone driver. It provides mic bias, analog inputs, line outputs, and programmable analog paths with volume/mute controls. The device is controlled over I2C and streams audio to a host via a digital audio interface (I2S/PCM). It runs from a single low-voltage supply and includes power-down modes for battery-powered designs. The IRHBR suffix denotes a specific RoHS/compliant package variant (tape/reel packaging); see TI’s packaging data for exact form factor. Typical applications include portable media players, voice recorders, and embedded audio in handheld electronics requiring an integrated, flexible CODEC.
Features
Key features of TLV320AIC26IRHBR:
- 2-channel stereo ADC and DAC
- 24-bit resolution; up to 96 kHz sampling rate
- I2C (register-based) control interface
- Digital audio interface: I2S, left-justified, or right-justified (master/slave modes)
- Analog front end: differential microphone bias and mic preamp; stereo line-in
- Headphone driver and line-out with programmable gain
- On-chip digital processing: volume control, mute, de-emphasis, bass boost, and pop-noise reduction
- Low-power operation; flexible clocking with MCLK input and PLL options
- Small footprint in IRHBR package suitable for mobile/compact devices
These summarize the codec’s core capabilities for typical consumer/mobile audio applications.
