PT2399 Reverberation Board with Microphone - (AD56858)

Description:

The PT2399 is a single-chip echo processor that uses CMOS technology. It accepts the analog audio input signal, a high sampling frequency ADC transfers the analog signal to a bit stream, which is then stored in the internal 44 Kbit RAM. After processing, the bit stream is demodulated by the DAC and the low-pass filter. The overall delay time is determined by the internal VCO clock frequency, and the user can easily change the VCO frequency by changing the external resistor, in this case, the external potentiometer. The PT2399 features low distortion (THD <0.5%@0.5Vrms) and low noise (No <-90dBV) for audio purposes, and the pin arrangement and application circuit are optimized for easy PCB design and cost-saving advantages.
