TPA6111A2DR Description

Short technical summary and product information.

The TPA6111A2DR 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 amplifier is designed for analog input and is fully specified for 3.3-V and 5-V operation, with functionality down to 2.5 V.

Key electrical characteristics include low total harmonic distortion plus noise (THD+N). When driving a 16-ohm load from 5 V, THD+N is 0.03% at 1 kHz and less than 1% across the audio band (20 Hz to 20 kHz). For 32-ohm loads, THD+N is less than 0.02% at 1 kHz and less than 1% across the audio band. For 10-kohm loads, THD+N is 0.005% at 1 kHz and less than 0.5% across the audio band.

The amplifier gain is externally configurable via two resistors per input channel, supporting settings from 0 to 20 dB without requiring external compensation. It also features internal midrail generation and a pop reduction circuit.

Available in surface-mount packaging, including HVSSOP (DGN) and SOIC (D) options, the TPA6111A2DR is suitable for various audio applications where compact size and reliable performance are required. It is pin-compatible with TPA122, LM4880, and LM4881 in the SOIC package.
