TAS5622ADDV

Overview

The TAS5622ADDV is a Texas Instruments Class-D audio amplifier power stage in an HTSSOP-44 package. It delivers 125 W stereo or 250 W mono output with PurePath HD digital input architecture. Key electrical parameters include 0.025% THD+N, 20 mA operating supply current, and operation from -40°C to +125°C.

Feature Summary

• PurePath HD digital input architecture for high-fidelity audio processing
• Integrated on-chip feedback loop for low distortion and high power supply rejection
• Supports bridge-tied load (BTL) stereo and parallel BTL mono configurations

Applications

• High-power home theater systems
• AV receivers
• Active subwoofers
• Professional audio equipment

Procurement Notes

Verify the specific suffix 'ADDV' against the official datasheet to confirm tube packaging and lead-free status. Ensure the design supports the required thermal dissipation for the HTSSOP-44 package at maximum output levels. Confirm compatibility with the intended digital audio interface protocols before finalizing component selection.

Selection Notes

Select this component when high channel count and high power density are required in a single package. The integrated feedback reduces external component count compared to open-loop designs. Verify that the system power supply can handle the peak current demands of 125W per channel into the target load impedance.

Part Context

Part of the TAS5622A series, designed as a high-performance digital input power stage. It complements TI's PurePath HD ecosystem by providing robust amplification with minimal external filtering requirements. The device targets applications demanding high efficiency and low total harmonic distortion.

Replacement Considerations

TAS5612LADDVR offers similar performance with potential thermal or packaging variations. TAS5624ADDVR provides higher power output in a thermally enhanced package. Verify pinout compatibility and thermal management requirements when substituting.
