TLV320AIC3101IRHBT

Codecs Overview

The TLV320AIC3101IRHBT is a low-power stereo audio codec manufactured by Texas Instruments, designed for portable audio and telephony applications. It features a single analog-to-digital converter (ADC) and two digital-to-analog converters (DACs), supporting resolutions up to 24 bits and conversion rates of 96 kHz. The device operates within an analog supply voltage range of 2.7 V to 3.6 V and a digital supply voltage range of 1.65 V to 1.95 V. It supports serial interfaces including I2C for control and PCM/I2S for audio data. Key performance metrics include a typical signal-to-noise ratio of 92 dB for the ADC and 102 dB for the DAC, with dynamic ranges of 93 dB and 97 dB respectively. The component is housed in a 32-pin VQFN package.

Codecs Feature Summary

• Integrated automatic gain control (AGC) and noise gate threshold management for the stereo audio ADC input path.
• Supports multiple digital audio interface modes including right-justified, left-justified, I2S, DSP mode, and TDM data transfer.
• Includes analog fully differential line output drivers and high-power output drivers with short-circuit protection.

Codecs Applications

• Portable audio devices requiring low power consumption
• Telephony systems utilizing stereo audio processing
• Embedded audio solutions with jack or headset detection needs

Codecs Procurement Notes

Verify the specific suffix IRHBT corresponds to the 32-VQFN package and industrial temperature range when sourcing. Confirm that the required supply voltages align with the specified analog and digital rails. Ensure ESD precautions are taken during handling due to moisture sensitivity. Cross-reference the datasheet revision history to confirm compatibility with existing design implementations.

Codecs Selection Notes

Select this component when a stereo codec with integrated AGC and high dynamic range is required for portable designs. Compare against the TLV320AIC3100 series if lower voltage operation or different pin configurations are needed. Verify that the 24-bit resolution and 96 kHz sampling rate meet the system's audio quality requirements. Check interface compatibility with the host processor's serial ports.
