IC PT2399 SMD

The PT2399 SMD is an Echo Processor IC that is often used in audio circuits to produce digital delay. The IC accepts analog audio input and transforms it into a digital stream of bits, which it then delays digitally. The output of this audio delayed audio signal is subsequently delivered. The PT2399 is a Princeton-made Echo Processor IC from the 1970s. The PT2399 has a number of interesting features. It’s a digital delay that closely resembles analog delays, with a warm bassy filter applied to the total delay repetitions.

Furthermore, the PT2399 contains a lot of high-frequency digital noise that finds its way into the audio line and is filtered out thanks to the on-chip op-amps. Because the PT2399 is a CMOS device, experimenting with it is a breeze. CMOS is an IC technology that, to put it simply, gets along with other CMOS devices. Meanwhile, instead of employing a microcontroller, these IC are frequently utilized for prototyping basic circuits.
