PA7493 Description
UTC PA7493 provides precise DC volume control, and a stereo bridged audio power amplifiers capable of producing 2W into 4Ω as a monolithic integrated circuit. In stand-by the power consumption is very low. UTC PA7493 bines a stereo single-end (SE) mode for headphone drive into a single chip and a stereo bridge-tied loads (BTL) mode for speaker drive(both modes are easily switched by the SE/BTL input control signal)...
