TLV320AIC3106IRGZR

Codecs Overview

The TLV320AIC3106IRGZR is a low-power stereo audio CODEC designed for portable audio and telephony applications. It integrates two ADCs and two DACs with a resolution of up to 24 bits, supporting sampling rates up to 96 kHz. The device operates on a supply voltage range of 1.1 V to 3.6 V, with specific analog supplies between 2.7 V and 3.6 V and digital supplies between 1.65 V and 1.95 V. It features an SNR of 92 dB for the ADC and 102 dB for the DAC. Communication is handled via I2C or SPI interfaces. The component is housed in a 48-pin VQFN package (7x7 mm) and functions within a temperature range of -40°C to +85°C.

Codecs Feature Summary

• Integrates dual high-performance analog-to-digital and digital-to-analog converters for stereo signal processing.
• Supports flexible digital audio interface protocols including I2S, DSP, and TDM modes.
• Includes integrated programmable gain amplifiers and headphone drivers to reduce external component count.
• Features comprehensive power management capabilities with multiple shutdown modes for battery-operated devices.

Codecs Applications

• Portable media players and MP3 devices
• Mobile phones and smartphones
• Voice-over-IP (VoIP) handsets

Codecs Procurement Notes

Verify the suffix IRGZR indicates the reel packaging format when ordering. Confirm the operating voltage requirements match the system design, specifically the 1.1 V to 3.6 V range. Ensure ESD precautions are taken during handling due to the moisture sensitivity level. Cross-reference the datasheet revision date to ensure compatibility with existing firmware configurations.

Codecs Selection Notes

Select this component for applications requiring high audio fidelity with low power consumption. The 24-bit resolution and high SNR make it suitable for premium audio experiences. Consider the 48-VQFN package size for space-constrained PCB layouts. Verify that the host processor supports the required I2C or SPI communication speeds for register configuration.

Codecs Part Context

This part belongs to the Texas Instruments TLV320AIC3106 family of low-power stereo audio CODECs. It is functionally similar to the TLV320AIC3106IZXHR but differs in package type and pinout. The IRGZR variant specifically denotes the tape and reel packaging option, distinguishing it from cut-tape or tray distributions found in other suffixes.

Codecs Replacement Considerations

The TLV320AIC3106IRGZT serves as a cut-tape alternative with identical electrical characteristics. For pin-compatible upgrades, consider the TLV320AIC3104-Q1 for automotive-grade requirements. Direct replacements must maintain the 48-VQFN footprint and support 24-bit stereo conversion.
