TLV320AIC33IRGZT

Codecs Overview

The TLV320AIC33IRGZT is a low-power stereo audio codec manufactured by Texas Instruments, designed for portable applications. It features a 24-bit resolution and supports sampling rates up to 96 kHz. The device integrates two analog-to-digital converters (ADCs) and two digital-to-analog converters (DACs). It communicates via serial interfaces including I2C and SPI. The operational supply voltage ranges from 1.1 V to 3.6 V, with an operating temperature range of -40°C to +85°C. Encased in a 48-pin VQFN package, it delivers high audio performance with a signal-to-noise ratio of 92 dB for the ADC and 100 dB for the DAC.

Codecs Feature Summary

• Integrates dual ADCs and dual DACs for stereo audio processing within a compact form factor.
• Supports flexible digital interface connectivity through I2C and SPI protocols for system control and data transfer.
• Operates across a wide voltage range to accommodate various power supply configurations in portable devices.

Codecs Applications

• Portable media players and handheld audio devices
• Mobile communication terminals requiring integrated audio codecs
• Digital voice recording equipment

Codecs Procurement Notes

Verify the specific suffix 'TG4' against the datasheet to confirm RoHS compliance and lead-free status. Ensure the VQFN-48 package dimensions match the PCB footprint requirements. Confirm that the I2C/SPI address settings align with the system bus configuration before integration.

Codecs Selection Notes

Select this component when a balance between low power consumption and high-fidelity stereo audio is required. Compare SNR specifications against other models if higher dynamic range is needed. Verify that the 96 kHz maximum sampling rate meets the application's bandwidth requirements.

Codecs Part Context

This part belongs to the TLV320AIC33 series of low-power stereo codecs. It shares core architectural similarities with variants like the TLV320AIC33IGQE but differs in packaging and termination materials. The IRGZT designation specifically indicates the surface-mount VQFN package variant suitable for automated assembly processes.

Codecs Replacement Considerations

The TLV320AIC3106 offers similar stereo functionality but operates on a narrower voltage range. The TLV320AIC3268 provides higher resolution but requires a lower supply voltage. Cross-referencing pinouts and register maps is essential when substituting these alternatives.
