TPA6111A2 Description

Short technical summary and product information.

The TPA6111A2 from Texas Instruments is a stereo audio power amplifier capable of delivering 150 mW of continuous RMS power per channel into 16-ohm loads. This device is fully specified for 3.3-V and 5-V operation, and can operate down to 2.5 V, making it compatible with PC power supplies.

Key features include integrated pop reduction circuitry and internal midrail generation, simplifying external component requirements. The amplifier gain is externally configurable via two resistors per input channel, supporting gain settings from 0 to 20 dB without needing external compensation. It also incorporates thermal and short-circuit protection for enhanced reliability.

The TPA6111A2 is available in surface-mount packaging, specifically the 8-pin SOIC and 8-pin PowerPAD MSOP. Its pin compatibility with TPA122, LM4880, and LM4881 in the SOIC package offers design flexibility.

Applications for the TPA6111A2 include smart phones, wireless handsets, portable tablets, notebook PCs, and docking stations where compact, efficient audio amplification is required.
