The TPA112 from Texas Instruments is a stereo audio power amplifier designed for efficient audio amplification. It delivers 150 mW of continuous RMS power per channel into 8-Ω loads.
This amplifier operates from a wide supply voltage range of 2.5 V to 5.5 V, with full specifications provided for 3.3-V and 5-V operation. The gain is externally configurable using two resistors per input channel, ranging from 1 to 10, and does not require external compensation.
Key electrical characteristics include low total harmonic distortion plus noise (THD+N). When driving an 8-Ω load from 5 V, THD+N is 0.1% at 1 kHz and less than 2% across the 20 Hz to 20 kHz audio band. Performance improves with higher impedance loads, such as 32-Ω or 10-kΩ.
The TPA112 is packaged in an 8-pin PowerPAD™ MSOP and supports surface-mount assembly. It includes built-in thermal and short-circuit protection, enhancing its reliability in various applications.
