TLV320ADC3101IRGER

ADCs/DACs - Special Purpose Overview

The TLV320ADC3101IRGER is a stereo analog-to-digital converter (ADC) from Texas Instruments, designed for high-fidelity audio applications. It integrates two differential input channels with a 24-bit resolution and supports sampling rates up to 96 kHz. The device features a low-noise programmable gain amplifier (PGA) and a sigma-delta modulator architecture. It operates from a single 1.8V or 3.3V supply and includes an integrated digital interface compatible with standard I2S protocols. Key electrical characteristics include a dynamic range of 105 dB and a total harmonic distortion plus noise (THD+N) of -95 dB at typical operating conditions.

ADCs/DACs - Special Purpose Feature Summary

• Stereo 24-bit ADC with 96 kHz maximum sampling rate
• Integrated low-noise PGA with programmable gain settings
• Single-supply operation (1.8V or 3.3V)
• Standard I2S digital audio interface compatibility

ADCs/DACs - Special Purpose Applications

• Portable audio players and recorders
• Smartphones and tablets
• Voice recognition systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'RGERT' indicates tape-and-reel packaging when ordering. Confirm the operating temperature range matches the application requirements, as industrial variants may differ. Ensure the voltage supply levels align with the system design before procurement.

ADCs/DACs - Special Purpose Selection Notes

Select this component for stereo audio capture requiring high dynamic range in space-constrained designs. Compare against monolithic alternatives if only single-channel input is needed. Verify that the I2S interface timing meets the host processor's specifications.

ADCs/DACs - Special Purpose Part Context

This part belongs to the TLV320ADC31xx family of stereo audio ADCs. It shares architectural similarities with other members like the TLV320ADC3100 but offers specific pinout and feature configurations optimized for mobile and portable electronics.

ADCs/DACs - Special Purpose Replacement Considerations

Direct substitutes within the same family include the TLV320ADC3100. Cross-reference pinouts and software register maps before substitution to ensure compatibility with existing firmware and hardware layouts.
