Overview
UNISONIC TECHNOLOGIES CO.
, LTD PA7468 Preliminary 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 from 20dB (@DC_VOL=0V) to -80dB (@DC_VOL=3.
54V) with 32 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 by the SE/ BTL input control pin signal.
„ FEATURES * Low Operating Current: 9mA *Two Output Modes Allowable with BTL and SE Modes(chosen by SE/ BTL pin) *Low Current Consumption :1mA(in Shutdown Mode) *With Short Circuit Protection *With Thermal Shutdown Pro...
