TPA122D Description

Short technical summary and product information.

The TPA122D is a stereo audio power amplifier designed by Texas Instruments. It is capable of delivering 150mW of continuous RMS power per channel into 8-ohm loads. The amplifier gain is externally configurable, allowing for settings from 1 to 10 without requiring external compensation.

 

This audio amplifier offers excellent performance with a THD+N of 0.01% at 1 kHz and less than 0.02% across the audio band of 20 Hz to 20 kHz. It is fully specified for 3.3V and 5V operation and can operate down to 2.5V. The device includes features such as pop reduction circuitry, internal midrail generation, and thermal and short-circuit protection.

 

The TPA122D is available in surface-mount packaging, including 8-pin SOIC and 8-pin PowerPAD MSOP options. It is pin-compatible with the LM4880 and LM4881 in the SOIC package.
