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 4Ω load or 2.4W to a 3Ω 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.
