The UTC PA3202 is a monolithic integrated circuit that stereo bridged audio power amplifiers capable of producing 2 W into 3 with a 5V supply voltage or 800mW into 3 with a 3.3V supply voltage .The UTC PA3202 simplifies design and frees up board space for other features. Both of the depop circuitry and the thermal shutdown protection circuitry are integrated in UTC PA3202, that reduce clicks and pops noise during power up or shutdown mode operation.
