2W X 2 CLASS AB AUDIO

POWER AMPLIFIER (WITH

DC_VOLUME CONTROL)

DIP-16

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 combines 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) to simplify the audio

system design. Package size is not occupies PCB space cause the

built-in over-temperature protection. It is suitable for small or

portable products.
