The TPA112DR is a stereo, analog input, Class-AB audio amplifier from Texas Instruments. It is designed to deliver 150 mW of continuous RMS power per channel into 8-ohm loads. The amplifier supports a wide range of supply voltages, operating from 2.5 V to 5.5 V, and is fully specified for 3.3-V and 5-V operation.
Gain is externally configurable using two resistors per input channel, without requiring external compensation for settings from 1 to 10. The TPA112DR includes thermal and short-circuit protection features. It is packaged in an 8-pin PowerPAD MSOP surface-mount package.
Total Harmonic Distortion plus Noise (THD+N) performance varies with load and frequency. When driving an 8-ohm load from 5V, THD+N is 0.1% at 1 kHz and less than 2% across the audio band. For 32-ohm loads, THD+N is less than 0.06% at 1 kHz and less than 1% across the audio band. For 10-kohm loads, THD+N is 0.01% at 1 kHz and less than 0.02% across the audio band.
This amplifier is suitable for various audio applications requiring moderate power output and good distortion performance within a compact footprint.
