Satellite + Subwoofer 3-Speaker System Electronic Crossover IC

Preliminary PT2352

DESCRIPTION

PT2352 is a 3-speaker system electronic crossover IC utilizing CMOS Technology specially designed

for the new generation of audio equipments. 3-channel electronic volume control, 2-channel 2nd order

high pass filter, 2nd order low pass filter and one mono subwoofer audio output are incorporated into a

single high performance chips. PT2352 combines the electronic volume controller and crossover

circuitry without MCU handling. Pin assignments and application circuit are optimized for easy PCB

layout and cost saving advantages.
