TSCS42A2X1NLGXZAX

Overview

The TSCS42A2X1NLGXZAX is a low-power, high-fidelity integrated CODEC featuring 32-bit stereo playback and recording. It integrates a true cap-less headphone amplifier and a filterless DDX™ Class-D speaker driver delivering 3W per channel into 4Ω loads. The device supports sample rates from 8kHz to 96kHz with I2S, Left-Justified, Right-Justified, and Bluetooth PCM interfaces. Key specifications include 124dB SNR for DACs and 90dB SNR for ADCs. It operates on a 1.8V digital supply and a 1.7V analog supply within a 48-lead 7x7mm QFN package.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout compatibility and thermal characteristics. Ensure the component meets RoHS requirements for your target market. Confirm moisture sensitivity levels and recommended reflow temperature profiles prior to assembly to prevent package damage during soldering processes.

Selection Notes

Select this component for designs requiring integrated audio processing and output stages in a compact form factor. The inclusion of a built-in DSP engine reduces external processor load. Verify that the required power supply rails (1.8V digital, 1.7V analog) are available in the system architecture. Ensure the application supports the necessary I2C control interface for configuration.

Part Context

This part belongs to the TSCS42xx series of portable consumer codecs from Tempo Semiconductor. The series is designed for battery-powered devices where power efficiency and audio fidelity are critical. The TSCS42A2 variant specifically includes the enhanced audio processing features and dual-channel output capabilities suitable for stereo applications.

Replacement Considerations

Direct replacements must match the 48-lead QFN package and electrical specifications. Check datasheets for compatible parts offering similar SNR values and integrated amplifier capabilities. Verify register compatibility if replacing in an existing design to minimize software changes.
