TLV320AIC26IRHBRG4

Codecs Overview

The TLV320AIC26IRHBRG4 is a low-power stereo audio CODEC manufactured by Texas Instruments. It features one ADC and two DACs with a resolution of 32 bits. The device supports serial interfaces including 4-Wire SPI. It operates within a power supply voltage range of 2.7 V to 3.6 V. The signal-to-noise ratio is specified at 92 dB for the ADC and 97 dB for the DAC. The maximum conversion rate is 53 kHz. It functions in temperatures from -40°C to +85°C and is housed in a 32-pin VQFN package.

Codecs Feature Summary

• Stereo audio processing with integrated analog-to-digital and digital-to-analog conversion capabilities
• Support for standard serial communication protocols including 4-Wire SPI
• Low power consumption design suitable for portable applications

Codecs Applications

• Portable multimedia devices requiring stereo audio input and output
• Voice recognition systems utilizing low-power audio capture
• Consumer electronics with limited power budgets

Codecs Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and green material status as per manufacturer documentation. Confirm the IRHB variant corresponds to the correct temperature grade and packaging format. Ensure compatibility with existing system power rails operating between 2.7 V and 3.6 V. Check for moisture sensitivity level requirements during storage and handling procedures before assembly.

Codecs Selection Notes

Select this component when a single ADC channel suffices for stereo reconstruction or when cost optimization is prioritized over dual-ADC architectures. Compare against the TLV320AIC3101 if higher resolution or different interface options are required. Evaluate power constraints against the 2.7 V minimum supply requirement. Consider the 32-bit resolution capability for high-fidelity audio paths.

Codecs Part Context

This part belongs to the TLV320AIC26 series of low-power audio codecs. It shares the core architecture with the non-G4 variants but includes specific environmental compliance markings. The device is distinct from the TLV320DAC26 which focuses solely on digital-to-analog conversion. It serves as a complete solution for stereo audio interfacing in embedded systems.

Codecs Replacement Considerations

The TLV320AIC26IRHBR is listed as a direct substitute. Verify pinout and electrical specifications match exactly before substitution. Ensure the replacement part meets the same industrial temperature range and package dimensions.
