2-W STEREO AUDIO POWER
AMPLIFIER WITH MUTE
CMOS IC
„ DESCRIPTION
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 3with 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.
A MUX control terminal (HP/LINE) allows selection between the
two sets of stereo input signals. To simplify the audio system
design, UTC PA3202 combines a stereo bridge-tied loads
(BTL)mode for speaker drive and a stereo single-end (SE)mode for
headphone drive into a single chip, where both modes are easily
switched by the SE/BTL input control pin signal.
