Overview
The TAS5701PAPRG4 is a stereo digital audio power amplifier manufactured by Texas Instruments. It delivers 20 watts of output power and utilizes I2S digital input for audio processing. The device operates within a supply voltage range of 4.5 V to 26 V and supports load impedances of 4 Ω or 8 Ω. It functions in Class-D topology with hardware-controlled configuration options. The component is housed in a 64-pin HTQFP package and is rated for an operating temperature range from 0 °C to 85 °C.
Feature Summary
- Integrates stereo Class-D amplification with direct I2S digital interface support
- Features hardware-controlled configuration for simplified system integration
- Provides high-efficiency audio output suitable for portable and fixed applications
Applications
- Portable media players and smartphones
- Tablets and handheld gaming devices
- Digital audio speakers and soundbars
- Car infotainment systems
Procurement Notes
Verify the complete part number including the G4 suffix, which indicates lead-free and RoHS compliance. Confirm the package type matches the design requirements, as variations exist within the series. Ensure the supplier provides valid traceability documentation. Cross-reference the datasheet revision date to confirm technical accuracy. Validate that the specific variant aligns with the intended hardware control scheme.
Selection Notes
Select this component when a stereo digital audio solution with integrated Class-D amplification is required. It is suitable for designs needing direct I2S connectivity without external DACs. Consider the thermal performance and PCB layout constraints associated with the HTQFP-64 package. Evaluate the power supply requirements against the 4.5 V to 26 V operating range. Compare efficiency metrics against alternative solutions if battery life is a critical constraint.
Part Context
This device belongs to the TAS570x family of digital audio power amplifiers from Texas Instruments. The family includes variants such as the TAS5706 and TAS5711, which share similar Class-D architectures but differ in channel count and power output capabilities. The TAS5701 specifically targets stereo applications requiring moderate power delivery in compact form factors.
Replacement Considerations
The TAS5701PAPR is the non-RoHS compliant predecessor to the TAS5701PAPRG4. Verify pinout compatibility before substitution. Other family members like the TAS5706 offer different power configurations.
