Overview
The TPA6111A2DGN is a stereo audio power amplifier produced by Texas Instruments. It is available in either an 8-pin SOIC or an 8-pin PowerPAD MSOP package. This amplifier is capable of delivering 150 mW of continuous RMS power per channel into 16-Ω loads. The device is fully specified for operation at 3.3 V and 5 V, making it suitable for a variety of applications including PC and mobile devices. The amplifier gain is externally configured using two resistors per input channel, and it does not require external compensation for settings of 0 to 20 dB.
