Product description
Classic digital delay chip with lots of lo-fi character. The circuit was originally created for karaoke machines and the like, but has been used in many synthesizers, effects pedals, Eurorack modules, etc.
Built-in A/D and D/A converters and antialiasing filter.
The delay time can be controlled with a resistor (e.g. a potentiometer), voltage controlled via a transistor, or with an external clock.
The PT2399 is found in many different DIY projects.
Operates on 5V. Current consumption is normally 15mA.
