STEREO 2.6W AUDIO POWER

AMPLIFIER WITH DC VOLUME

CONTROL

DESCRIPTION

As an audio power amplifier with DC volume control, UTC

PA7468 is a stereo bridged audio power amplifier. In normal operation

it can produce 2.6Ω (1.8W) into 4W with less than 10% (1.0%)

THD+N.

In UTC PA7468, the attenuator range of the volume control is

steps. Besides, the UTC PA7468 includes the depop circuitry and the

thermal shutdown protection circuitry (to reduce pops and clicks noise

during power up or shutdown mode operation).

The UTC PA7468 has a BTL mode for speaker drive and a SE

mode for headphone drive. These tow modes can be quickly chosen

FEATURES
