PT2398 Echo/Surround Processor

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 freque.
