PT2399 Product Details

The PT2399 is a CMOS single-chip cho/delay processor IC. Within this digital chip lies an ADC (Analog to Digital converter), 44Kb of RAM dedicated to sample storage, and a DAC (Digital to Analog converter). While initially designed as a straightforward solution for introducing delay, reverb, or echo effects into karaoke and entertainment setups, it quickly gained acclaim within the guitar pedal community. Its prowess lies in its ability to replicate BBD-based delay circuits, affordability, user-friendly through-hole packaging, compatibility with a 5V power supply, and adaptability to modifications. The PT2399 is renowned for its exceptional performance, characterized by minimal distortion (THD<0.5%) and extremely low noise levels (No<-90dBV). These qualities result in the production of top-tier audio output. Furthermore, the pin assignments and application circuit have been thoughtfully designed to facilitate a straightforward PCB layout, providing a cost-saving advantage. For more details about the circuit, power supply, check the PT2399 datasheet.

FAQs


What are the Functions of Pins 15 and 16 in a PT2399 Circuit?

Pins 15 and 16 in a PT2399 circuit collaborate to create a capacitance effect by modifying the external resistance. This alteration adjusts the input frequency response of the inverting amplifier, serving as the signal input.

What is the use of PT2399?

The PT2399 stands as a singular integrated circuit (IC) echo processor, harnessing the power of CMOS technology. Its primary function is to accept analog audio input signals. A high sample rate ADC converts these analog signals into a bitstream, which is then stored in an internal 44Kbit RAM. Following this, the bitstream undergoes demodulation by a DAC and low-pass filter.

How Does the PT2399 Operate?

In the PT2399, digitization is solely employed for signal delay, without any additional sound processing. This versatile IC briefly stores a sound sample in memory for a few milliseconds, subsequently playing it back without any sound alterations. All sound processing is handled entirely by a 100% analog circuit.
