TLV320DAC3203IRGER

Overview

The TLV320DAC3203IRGER is an ultra-low power stereo audio codec manufactured by Texas Instruments. It integrates two analog-to-digital converters and two digital-to-analog converters with a 24-bit resolution and support for sampling rates up to 96 kHz. The device operates on a single supply voltage ranging from 1.71 V to 3.6 V and features integrated headphone amplifiers. It utilizes I2C and SPI serial interfaces for control and data transmission, functioning within a temperature range of -40°C to +85°C in a VQFN-48 package.

Feature Summary

• Integrates dedicated headphone amplifiers for direct speaker driving without external components
• Supports low-power operation suitable for battery-powered portable devices
• Provides high-fidelity audio conversion with 24-bit resolution

Applications

• Mobile handheld communication devices
• Portable media players
• Voice-over-IP (VoIP) equipment

Procurement Notes

Verify the specific suffix IRGER against the manufacturer datasheet to confirm the tape-and-reel packaging configuration and commercial grade temperature rating. Ensure compatibility with system voltage rails and interface protocols before integration. Cross-reference the component marking code with official documentation to authenticate the source and prevent counterfeit substitution.

Selection Notes

Select this component when an integrated solution combining ADC/DAC functions with output amplification is required. It is appropriate for designs prioritizing minimal bill-of-materials count and reduced board space. Consider its power consumption profile relative to other codecs in the TLV320 family if extended battery life is critical.

Part Context

This part belongs to the TLV320DAC32 series of ultra-low power stereo audio codecs. It shares functional similarities with the TLV320AIC28 and TLV320AIC29 but distinguishes itself through optimized power management and integrated output stages designed specifically for mobile and consumer electronics applications requiring compact form factors.

Replacement Considerations

Direct replacements include the TLV320DAC3203IRGET and TLV320DAC3203IRGER.A variants, which share identical electrical characteristics and pinouts.
