DUAL 2.6W AUDIO POWER

AMPLIFIER WITH FOUR

SELECTABLE GAIN SETTINGS

AND INPUT-MUX CONTROL

DESCRIPTION

The UTC PA3312 is a monolithic integrated circuit that stereo

bridged audio power amplifiers capable of producing 2.6W into 3Ω

with less than 10% THD+N or 1W into 8Ω with less than 0.65%

THD+N. This device minimizes the number of external components

needed, simplifying the design, and freeing up board space for

other features. Both of the depop circuitry and the thermal

shutdown protection circuitry are integrated in UTC PA3312, that

reduce pops and clicks noise during power up or shutdown mode

operation .

*Pb-free plating product number: PA3312L

Amplifier gain is internally configured and controlled by way of

two terminals (GAIN0 and GAIN1). BTL gain setting of 6 dB, 10 dB,

15.6dB, 21.6dB (inverting) are provided, whereas SE gain is

always configured as 4.1dB for headphone drive. A MUX control

terminal (HP/LINE) allows selection between the two sets of stereo

input signals. To simplify the audio system design, UTC PA3312

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.

FEATURES

* Low operating current with 10mA

* Compatible with pc 99 desktop line-out into 10KΩ load

* Internal gain control ,which eliminates external gain-setting

resistors

* 2.6w per channel output power into 3Ω at 5V , BTL mode

* Input MUX select terminal

* Pc-beep input

* Improves depop circuitry to eliminate turn-on and turn-off

transients in output

* Fully differential input
