Echo/Surround Processor
Description
PT2398
PT2398 is an echo/surround audio processor IC utilizing CMOS Technology and is
functionally compatible with ES56028. Equipped with ADC and DAC, it uses digital
processing to generate the delay time, which in turn, can be controlled manually or by a micro
controller. PT2398 also features an internal VCO circuit in the system clock, thereby, making
the frequency easily adjustable. The pin assignments and application circuit are optimized for
easy PCB layout and cost saving advantage.
