PT2390
Echo IC with Built-in Microphone Amplifier & Output Mixer
DESCRIPTION
PT2390 is a digital echo IC utilizing CMOS Technology. Microphone Amplifier, Output Mixer, internal
44K RAM and Vocal Switch are all integrated in a single chip to provide a digital echo IC of the the highest
standard. Very low distortion and high S/N Ratio qualities, not to mention the built-in VCO feature which
eliminates the need for an external crystal oscillator are just some of the features of PT2390. Pin assign-
ments and application circuit are optimized for easy PCB Layout and low cost effectiveness.
