PA3202
2-W STEREO AUDIO POWER
AMPLIFIER WITH MUTE
DESCRIPTION
The UTC
PA3202
is a monolithic integrated circuit that stereo
bridged audio power amplifiers capable of producing 2 W into 3鈩?/div>
with a 5V supply voltage or 800mW into 3鈩?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.
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.
