TAS5751MDCA

Overview

The TAS5751MDCA is a digital input Class-D audio power amplifier designed for stereo speaker applications. It operates in bridge-tied load (BTL) configuration for stereo output or parallel BTL mode to drive single low-impedance loads with higher power. The device accepts wide-range serial data inputs and integrates a fully programmable data path. Key electrical parameters include a 25 W stereo output power at 8 Ohms, a THD+N of 0.1%, and an operating supply voltage range from 3 V to 3.6 V. It functions within a temperature range of 0°C to +85°C and is housed in a 48-pin HTSSOP package.

Feature Summary

• Supports stereo operation in bridge-tied load (BTL) configuration or parallel BTL mode for high-power single-load driving.
• Features a fully programmable data path that routes discrete audio channels from serial data inputs to internal drivers.
• Integrates seamlessly with most digital audio processors and MPEG decoders via standard serial interfaces.

Applications

• Driving stereo speakers in home theater systems
• Powering multi-channel audio setups in automotive infotainment units
• High-fidelity digital audio playback in consumer electronics

Procurement Notes

Verify the specific suffix 'MDCA' against official Texas Instruments documentation to confirm the tube packaging format and commercial grade temperature rating. Ensure compatibility with the required 48-pin HTSSOP footprint during PCB layout. Cross-reference the datasheet revision date to validate all electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when a digital input interface is preferred over analog inputs to reduce noise susceptibility. It is suitable for designs requiring efficient Class-D amplification with integrated digital signal routing. Consider the 48-pin package size constraints and the specific supply voltage requirements of the target system architecture.

Part Context

This part belongs to the TAS5751M series of digital audio power amplifiers from Texas Instruments. The series is characterized by high efficiency and flexible configuration options for driving various speaker loads. The TAS5751MDCA specifically denotes the commercial grade variant in tube packaging, distinct from the tape-and-reel version.

Replacement Considerations

TAS5751MDCAR serves as the direct functional equivalent in tape-and-reel packaging. Other members of the TAS575xM family may offer different power outputs or thermal characteristics but require verification of pinout and register compatibility.
