Satellite + Subwoofer 3-Speaker System Electronics Crossover IC
DESCRIPTION
PT2353H 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. PT2353H 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.
