UDA1344TS/N2,512

Overview

The UDA1344TS is a low-voltage, low-power stereo audio CODEC with integrated DSP features. It employs bitstream conversion techniques for high-fidelity analog-to-digital and digital-to-analog conversion. The device supports sampling frequencies from 8 to 55 kHz with system clocks of 256fs, 384fs, or 512fs. It accepts I2S, MSB-justified, and LSB-justified data formats up to 20 bits. Key electrical parameters include an ADC signal-to-noise ratio of 95 dB and a DAC signal-to-noise ratio of 100 dB. Power supply voltages range from 2.7 V to 3.6 V for all domains. Total power consumption in record and playback mode is typically 69 mW.

Feature Summary

• Integrated digital sound processing including tone control, bass boost, treble, and soft mute via L3 interface.
• Supports multiple serial data formats including I2S-bus, MSB-justified, and LSB-justified configurations.
• Features separate power control for ADC and DAC sections to optimize energy efficiency.
• Includes non-inverting ADC with integrated DC cancellation filter and overload detection.

Applications

• Portable digital audio equipment requiring recording and playback functions
• Low-voltage consumer audio systems
• Digital voice processing applications

Procurement Notes

Verify component authenticity through authorized NXP distributors or certified suppliers. Confirm the part number matches UDA1344TS/N2,512 exactly. Check for RoHS compliance documentation as indicated in manufacturer records. Ensure storage conditions adhere to moisture sensitivity level specifications. Review datasheet revisions to confirm functional compatibility with current design requirements.

Selection Notes

Select this component for designs requiring stereo audio conversion with minimal external filtering. The integrated operational amplifiers eliminate the need for post-filter components at the DAC output. Consider the L3 interface for microcontroller-controlled DSP adjustments such as volume and equalization. Verify that the host processor supports the required serial data formats and clock speeds. Ensure power supply rails match the 2.7 V to 3.6 V operating range.

Part Context

The UDA1344TS belongs to the UDA134 family of audio codecs from NXP Semiconductors. It is pin and function compatible with the UDA1340M when operated in L3 mode. The device utilizes SSOP28 packaging, designated as SOT341-1. It represents a solution for integrating high-performance audio conversion with digital signal processing in compact form factors.

Replacement Considerations

The UDA1340M is confirmed as a pin and function compatible replacement when used in L3 mode. Verify specific voltage scaling differences between the DAC outputs of both devices before substitution.
