TSCS42A2X1NLGIZAX

Overview

The TSCS42A2X1NLGIZAX 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 3W/channel DDX™ Class-D speaker driver for 4Ω loads. The device supports sample rates from 8kHz to 96kHz with stereo 32-bit DACs providing 124dB SNR and ADCs offering 90dB SNR. Digital audio interfaces include I2S, Left-Justified, Right-Justified, TDM, and direct Bluetooth PCM modes. Control is managed via an I2C-compatible interface, and the unit operates on 1.8V digital and 1.7V analog supplies within a 48-lead 7x7mm QFN package.

Procurement Notes

Verify component authenticity by checking the manufacturer marking against official datasheet specifications. Confirm the specific ordering suffix matches the required package and temperature range. Request the original datasheet directly from Tempo Semiconductor or authorized distributors to ensure technical accuracy before finalizing procurement orders.

Selection Notes

Select this component when a single IC solution is required for both audio conversion and power amplification in space-constrained designs. Ensure the design accommodates the 1.8V digital and 1.7V analog supply requirements. Verify that the host processor supports the desired digital audio interface format, such as I2S or Bluetooth PCM, for proper system integration.

Part Context

This part belongs to the TSCS42xx series of portable consumer codecs from Tempo Semiconductor. The series focuses on integrating high-fidelity audio processing with power amplification to reduce bill-of-materials costs. The TSCS42A2 variant specifically includes the DDX™ Class-D amplifier functionality alongside the standard codec features.

Replacement Considerations

Direct pin-to-pin replacements are not explicitly listed in public documentation. Evaluate alternative Tempo Semiconductor codec families or multi-function audio ICs based on matching pinout, supply voltage, and package dimensions.

FAQ

Does the TSCS42A2 support direct Bluetooth PCM input?

Yes, the digital audio data ports support direct Bluetooth PCM mode in addition to standard I2S, Left-Justified, Right-Justified, and TDM formats.

What is the maximum output power of the integrated speaker driver?

The integrated DDX™ Class-D speaker driver delivers 3W per channel into a 4Ω load.

How is the audio output processing controlled?

The built-in Audio Output Processing (AOP) DSP engine is tunable using the Windows-based Tempo ASC GUI software.
