TPA005D12DCA

Overview

The TPA005D12 is a monolithic stereo Class-D audio power amplifier designed for high efficiency. It delivers up to 2 W of continuous average power into a 4-ohm load at 0.5% THD+N from a 5-V supply. The device operates with a single power supply and utilizes a bridge-tied load (BTL) configuration, eliminating the need for external output coupling capacitors. It features a thermally enhanced 48-pin PowerPAD TSSOP surface-mount package.

Feature Summary

Extremely efficient Class-D stereo operation using power DMOS transistors
Bridge-tied load (BTL) configuration eliminates external output coupling capacitors
Chip-level shutdown control limits quiescent current to 0.2 mA
Integrated thermal, over-current, and under-voltage protection circuitry

Applications

Battery-powered audio devices
High-fidelity audio systems
Portable electronic equipment
