PT2399 Digital Delay Echo Audio IC

Description

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 Specifications: Parameter Value Supply Voltage 4.5V to 5.5V Supply Current 30mA (typical) Voltage Gain -0.5dB to 2.5dB Max Output Voltage 2.5Vrms (THD = 10%) Total Harmonic Distortion (THD) 0.3% to 1.0% Output Noise Voltage -90dBV (typical) Clock Frequency 2MHz to 10MHz Delay Time 31.3ms to 342ms Power Supply Rejection Ratio (PSRR) -30dB to -40dB Package Types DIP-16 Pin Configuration: Applications: Video tape recorders for audio enhancement. Video compact disk players for echo effects. Televisions for surround sound processing. CD players for delay functions. Car stereo systems for immersive audio. Karaoke mixers for vocal echoes. Electronic musical instruments for effects. Package Include: 1x PT2399 Echo Processor IC. Datasheet: PT2399
