Least external components
Auto reset function prevent pop noise
Low noise, SNR>0db
Lowe distortion, THD 0.5%
Adjustable VCO clock frequency
PT3 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 frequency easily adjustable.
PT3 boast of very low distortion (THD less 0.5%) and very low noise (No less -0dBV), thus producing
high quality audio output. The pin assignments and application circuit are optimized for easy PCB layout and
cost saving advantage.
