PA7469 Description

As an audio power amplifier, UTC PA7469 can provides precise DC volume control, and a stereo bridged audio power amplifiers capable of producing 2.6Ω(1.8W) into 4W with less than 10% (1.0%)THD+N. In UTC PA7469, the attenuator range of the volume control is from 20dB (DC_Vol=0V) to -80dB (DC_Vol=3.54V) with 32 steps. It also includes both of the depop circuitry and the thermal shutdown protection circuitry which can...
