TLV320ADC3100IRGET

ADCs/DACs - Special Purpose Overview

The TLV320ADC3100IRGET is a stereo audio analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a 24-bit resolution and supports sampling rates from 8 kHz to 96 kHz. The device operates on dual power supplies: 1.65 V to 1.95 V for digital logic and 2.7 V to 3.6 V for analog circuits. Key performance metrics include a signal-to-noise ratio (SNR) of 91 dB for the ADC and -85 dB THD+N. It utilizes I2C and I2S interfaces for control and data transmission, housed in a 24-VQFN package with an operating temperature range of -40°C to +85°C.

ADCs/DACs - Special Purpose Procurement Notes

Verify the suffix 'GER' corresponds to the specific tape-and-reel packaging variant. Confirm the 24-VQFN footprint matches the PCB design. Ensure voltage levels align with system requirements for both analog and digital domains.

ADCs/DACs - Special Purpose Selection Notes

Select this component when high-resolution stereo digitization is required within a compact form factor. Compare against the TLV320AIC3100 if DAC functionality is also needed. Verify that the 96 kHz maximum sample rate meets the application's bandwidth requirements.

ADCs/DACs - Special Purpose Part Context

This part belongs to the TLV320 family of low-power audio converters. It is functionally similar to the TLV320ADC3101 but may differ in pinout or specific feature sets. The IRGET suffix indicates a specific reel quantity and packaging type for surface-mount assembly.

ADCs/DACs - Special Purpose Replacement Considerations

The TLV320ADC3101IRGET is a potential substitute within the same family. Verify register compatibility and pin alignment before replacement. Other TI audio ADCs may require significant schematic and firmware changes.
