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.

FEATURES

* Operating voltage range V_DD=2V~5.5V

* Output power:

-2.4W(typ.)@5V into 3Ω with 1% THD+N max (1kHz)

-2.1W(typ.)@5V into 4Ω with 1% THD+N max (1kHz)

* Eliminates SE-mode output coupling capacitors

* Shutdown mode available

* click and pop reduction circuitry

* Unity-gain stable

* Thermal-shutdown Protection

* Input MUX control

* SE/BTL mode available
