PA4867
DUAL 2.1W AUDIO AMPLIFIER
PLUS STEREO HEADPHONE
FUNCTION
DESCRIPTION
The UTC
PA4867
is a stereo audio power amplifier capable of
delivering typically 2.1W to a 4鈩?load or 2.4W to a 3鈩?load each
channel with less than 1.0% THD+N using a 5V power supply. UTC
PA4867
has a new circuit topolopy which can eliminate headphone
output coupling capacitors. And an internal input MUX allows two
sets of stereo inputs to the amplifier.
The UTC
PA4867
has integrated depop circuitry that virtually
eliminates transients that cause noise in the speakers during power
up and when using the shutdown modes.
