Overview
The TAS5731PHPR is a digital audio power amplifier from Texas Instruments, packaged in HTQFP-48. It delivers up to 60 W of stereo output power with a THD+N of 10%. The device operates on a supply voltage range of 8 V to 24 V and supports I2S inputs at sampling rates from 8 kHz to 48 kHz. It features integrated DSP capabilities, including speaker EQ and dynamic range compression. The component functions within an operating temperature range of -40°C to +85°C and draws a typical operating current of 50 mA.
Feature Summary
- Integrates digital signal processing for speaker equalization and dynamic range control
- Supports 2.1 channel mode configuration for enhanced audio performance
- Accepts serial I2S digital audio input data streams
- Includes comprehensive protection mechanisms against over-current and thermal events
Applications
- LCD television systems
- LED television displays
- Sound bar audio modules
Procurement Notes
Verify the specific suffix 'PHPR' indicates tape-and-reel packaging rather than tray delivery. Confirm the manufacturer is Texas Instruments and that the part number matches the exact datasheet specifications for the TAS5731M series. Ensure compatibility with required I2C addressing and power supply voltages before integration.
Selection Notes
Select this component when high-efficiency digital amplification with built-in DSP is required. It serves as a direct replacement for the TAS5727 in compatible designs. Consider the HTQFP-48 package constraints and the need for external decoupling capacitors near power pins. Verify that the target application supports the specified 8 V to 24 V power rail requirements.
Part Context
This device belongs to the TAS5731M family of digital audio power amplifiers. It is designed for applications requiring efficient stereo sound reproduction with minimal external components. The integration of DSP functions reduces the need for separate audio processing units, simplifying the overall system architecture for consumer electronics manufacturers.
Replacement Considerations
The TAS5731 is pin-to-pin compatible with the TAS5727. Engineers can substitute one for the other in existing designs without modifying the PCB layout, provided the power supply and software configuration support the specific feature set of the chosen amplifier.
