TLV320AIC31IRHBTG4

Codecs Overview

The TLV320AIC31IRHBTG4 is a low-power stereo audio CODEC manufactured by Texas Instruments, designed for portable audio and telephony applications. It features a 24-bit resolution with a maximum sampling rate of 96 kHz. The device integrates two ADCs and two DACs, supporting an analog supply voltage range from 1.1 V to 3.6 V. It operates within a temperature range of -40°C to +85°C and utilizes a serial I2C interface for control. The component is housed in a 32-pin VQFN package, offering high signal-to-noise ratios of 92 dB for the ADC and 100 dB for the DAC.

Codecs Feature Summary

• Integrates stereo analog-to-digital and digital-to-analog converters for complete audio processing
• Supports low-voltage operation suitable for battery-powered portable devices
• Includes programmable gain amplifiers and mixers for flexible input/output routing

Codecs Applications

• Portable audio players and media devices
• Mobile telephones and smartphones
• Voice over IP (VoIP) terminals

Codecs Procurement Notes

Verify the G4 suffix indicates lead-free compliance and RoHS status against current manufacturer documentation. Confirm the specific tape and reel packaging details required for surface mount assembly processes. Ensure compatibility with existing design-in components regarding pinout and thermal requirements.

Codecs Selection Notes

Select this component when a stereo CODEC with 24-bit resolution and 96 kHz sampling is required. It is appropriate for designs needing integrated headphone drivers or line-level outputs with low power consumption. Consider the VQFN-32 package size constraints and the need for external passive components for filter implementation.

Codecs Part Context

This part belongs to the TLV320AIC31 series of low-power stereo audio CODECs. The G4 suffix typically denotes a lead-free and RoHS-compliant version of the standard TLV320AIC31IRHBT device. It shares functional similarities with other members of the family but may differ in specific electrical characteristics or packaging options.

Codecs Replacement Considerations

The standard TLV320AIC31IRHBT is the primary equivalent part number. Verify if the non-G4 version meets environmental compliance requirements for the target market.
