TLV320AIC3107IYZFT

Overview

The TLV320AIC3107IYZFT is a low-power stereo audio codec manufactured by Texas Instruments, designed for portable battery-powered applications. It integrates a stereo headphone amplifier and a mono Class-D speaker driver within a single package. The device supports high-performance audio conversion with up to 32-bit resolution and sampling rates from 8 kHz to 96 kHz. Key electrical specifications include a 97 dB A-weighted SNR for the DAC in single-ended mode and 92 dB A-weighted SNR for the ADC. It operates on a supply voltage range of 2.7 V to 5.5 V for the speaker amplifier and 2.7 V to 3.6 V for the analog power domain. The component is housed in a compact 42-DSBGA package measuring 3.563 mm x 3.376 mm with a 0.5 mm pin pitch.

Feature Summary

Procurement Notes

Verify the specific suffix 'IYZFT' against the manufacturer's official datasheet to confirm the industrial temperature grade, tape-and-reel packaging format, and lead finish specifications. Ensure compatibility with the required PCB footprint dimensions for the 42-DSBGA package before finalizing procurement orders.

Selection Notes

Select this component when a system requires integrated amplification for both headphones and speakers without external discrete components. It is suitable for designs needing flexible input configurations, supporting up to six single-ended or three fully differential inputs. Consider the power constraints of the application, as the device offers optimized low-power modes for extended battery life in portable electronics.

Part Context

This part belongs to the TLV320AIC3107 series of low-power stereo audio codecs from Texas Instruments. The series is engineered to provide high-fidelity audio performance while minimizing power consumption, making it ideal for mobile and handheld devices where space and energy efficiency are critical design parameters.

Replacement Considerations

Check for direct substitutes within the same family, such as the TLV320AIC3107YFFR, ensuring package and reel variations match. Verify that any alternative maintains the same 42-DSBGA form factor and electrical characteristics to ensure board-level compatibility.
