Product Summary

PT2399 is an echo audio processor chip using CMOS technology, equipped with ADC and DAC, high sampling frequency and 44K internal memory of the digital processing is used to generate the delay time, it also has an internal VCO circuit system clock, so that the frequency is easy to adjust. PT2399 has a very low distortion (THD <0.5%) and very low noise (no <-90dBV), to produce high quality audio output. Pin assignments and application circuit for easy PCB layout and cost saving advantages were optimized.
