PT2399-D Digital Delay IC

Updated: 2026-08-05

Overview

The PT2399-D is a digital delay integrated circuit widely used in audio signal processing. It is designed to produce echo and delay effects with minimal noise, making it a preferred choice for musical instruments, karaoke machines, and professional audio systems. This IC operates on low voltage and offers adjustable delay times, allowing for flexible integration into various audio devices. Its compact size and efficiency make it suitable for both consumer and industrial applications.

Structure and Working Principle

The PT2399-D consists of an analog-to-digital converter (ADC), a digital delay line, and a digital-to-analog converter (DAC). The incoming audio signal is converted to a digital format, processed to introduce a delay, and then reconverted to analog for output. The delay time is controlled by an external resistor or capacitor, enabling customization based on the application. The IC's internal architecture ensures low distortion and high signal integrity, critical for maintaining audio quality.
