TLV320AIC3110IRHBR

Overview

The TLV320AIC3110IRHBR is a low-power stereo audio codec manufactured by Texas Instruments, designed for portable and battery-operated applications. It features a single analog-to-digital converter (ADC) and two digital-to-analog converters (DACs), supporting high-resolution audio processing with up to 32-bit resolution. The device operates at sampling rates of up to 192 kHz and functions within a supply voltage range of 2.7 V to 3.6 V. It utilizes a serial I2C interface for control and communication. Key performance metrics include a signal-to-noise ratio of 91 dB for the ADC and 95 dB for the DAC, with total harmonic distortion plus noise specified at -85 dB for the ADC and -82 dB for the DAC. The component is housed in a compact 32-pin VQFN package suitable for surface mount technology.

Feature Summary

• Integrates one ADC and two DACs for stereo audio conversion capabilities
• Supports high-definition audio processing with resolutions up to 32 bits
• Operates on a single low-voltage power supply ranging from 2.7 V to 3.6 V
• Utilizes standard serial I2C interface for configuration and data transfer

Applications

• Portable media players and handheld audio devices
• Mobile phones and smartphones requiring low-power audio solutions
• Digital voice recorders and dictaphones
• Automotive infotainment systems with space constraints

Procurement Notes

Verify the specific suffix IRHBR corresponds to the required tape-and-reel packaging quantity when ordering. Confirm that the 32-VQFN footprint matches your PCB layout design rules. Ensure compatibility with the 2.7 V to 3.6 V supply rails available in your target system. Check moisture sensitivity level requirements for reflow soldering processes. Validate that the I2C address settings do not conflict with other peripherals on the bus.

Selection Notes

Select this component when a single ADC is sufficient for stereo input recording while dual DACs are needed for independent left and right channel playback. Consider the 192 kHz maximum sampling rate if high-fidelity audio reproduction is required. Evaluate the 91 dB/95 dB SNR specifications against your noise floor requirements. Compare the 32-VQFN package dimensions against available board space constraints relative to other codecs in the TLV320 family.

Part Context

This part belongs to the TLV320AIC3110 series of low-power audio codecs from Texas Instruments. It is distinct from higher-channel-count variants like the TLV320AIC3101, which features dual ADCs and dual DACs. The IRHBR suffix indicates the reel packaging format. It serves as a specialized solution for applications prioritizing power efficiency and minimal pin count over multi-channel input capabilities found in more complex audio subsystems.

Replacement Considerations

The TLV320AIC3110IRHB is a tube-packaged alternative offering identical electrical characteristics but different physical packaging. Verify pinout compatibility before substitution. No direct functional equivalents with different architectures are confirmed in public documentation.
