## Description

The TPA122DR is a stereo audio power amplifier designed by Texas Instruments, capable of delivering 150 mW of continuous RMS power per channel into 8-ohm loads. It is fully specified for operation with 3.3-V and 5-V power supplies and can operate down to 2.5 V. The amplifier features external gain configuration, pop reduction circuitry, and internal midrail generation.

Key electrical characteristics include a THD+N performance of 0.01% at 1 kHz and less than 0.02% across the audio band (20 Hz to 20 kHz) when driving 8-ohm loads. The device includes thermal and short-circuit protection for enhanced reliability.

The TPA122DR is available in surface-mount packaging, specifically an 8-pin SOIC or an 8-pin PowerPAD MSOP. It is pin-compatible with the LM4880 and LM4881 in the SOIC package, facilitating upgrades in existing designs.
