TLV320AIC26IRHB

The Texas Instruments TLV320AIC26IRHB is a low-power stereo audio CODEC designed for applications requiring high-quality audio conversion. It integrates a mono Analog-to-Digital Converter (ADC) and stereo Digital-to-Analog Converters (DACs), supporting sampling rates up to 48 ksps. This device offers a high-quality 97-dBA stereo audio playback performance with a typical DAC SNR of 97 dB and a typical ADC SNR of 92 dB.

Key features include an on-chip 325-mW speaker driver, a stereo headphone amplifier with a capless output option, and a microphone preamp with automatic gain control. The TLV320AIC26IRHB also incorporates an integrated Phase-Locked Loop (PLL) for flexible audio clock generation and programmable digital audio bass, treble, EQ, and de-emphasis controls. It supports direct battery measurement up to 6-V input and on-chip temperature measurement.

This audio CODEC operates within a temperature range of -40°C to 85°C and is supplied in a compact 32-pin 5x5 mm VQFN package suitable for surface mounting. The digital audio interface supports DSP, I2S, and L/R formats, while the control interface uses SPI. Its low power consumption, with only 11-mW for stereo audio playback at 48 ksps, makes it ideal for battery-powered devices.

Applications for the TLV320AIC26IRHB include cellular and smart phones, MP3 players, digital still cameras, and digital video camcorders.
