Description

General part information

TPA0162 Series

The TPA0162 is a stereo audio power amplifier in a 24-pin TSSOP thermally enhanced package capable of delivering 2.8 W of continuous RMS power per channel into 3-loads.

This device minimizes the number of external components needed, which simplifies the design and frees up board space for other features. When driving 1 W into 8-speakers, the TPA0162 has less than 0.22% THD+N across its specified frequency range. The integrated depop circuitry virtually eliminates transients that cause noise in the speakers.

The overall gain of the amplifier is controlled digitally by the UP and DOWN terminals. At power up, the gain is set at the lowest level, –85 dB. It can then be adjusted to any of 31 discrete steps by pulling the voltage down at the desired pin to logic low. The gain is adjusted in the initial stage of the amplifier as opposed to the power output stage. As a result, the THD changes very little over all volume levels.
