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.
