PT2399 Digital Delay Echo Audio IC
The PT2399 Digital Delay Echo Audio IC is a highly advanced echo processor IC that utilizes CMOS technology to provide high-quality audio effects. This IC processes an analog audio input signal, converting it into a bit stream using a high sample rate ADC. The bit stream is then stored in an internal 44Kbit RAM and, after processing, is de-modulated by a DAC and lowpass filter for optimal sound quality.
Features:
- CMOS technology
- Least external components
- Auto reset Function prevent POP noise
- Low noise, SNR better than 90dB
- Low distortion, THD= 0.5%
- User adjustable VCO clock frequency
