PT2399
DESCRIPTION
PT2399 is an echo audio processor IC utilizing CMOS Technology which is equipped with ADC and
DAC, high sampling frequency and an internal memory of 44K Digital processing is used to generate
the delay time, it also features an internal VCO circuit in the system clock, thereby, making the fre-
quency easily adjustable. PT2399 boast of very low distortion (THD<0.5%) and very low noise
(No<-90dBV), thus producing high quality audio output. The pin assignments and application circuit
are optimized for easy PCB layout and cost saving advantage.
