Description Ap9301 itf is an ultra-wideband phase delay with an ECL topology to ensure high-speed operation that accepts either single-ended or differential data input.

It provides high-quality recording and playback with a single to second message. Its high output voltage, excellent More information. Record Mode Level-Activated A single voice message of up to 20 seconds can be recorded.

When pins are connected as shown in this example,the operating modes are as follows: All other names mentioned in this document are More information. No recording or playback is allowed.

APR Recording IC – 16 sec ~ 30 sec recording and playback voice chip

The APR device stores and reproduces voice signals in their natural forms, eliminating distortion that is often introduced by encoding and compression. This is advanced information on a new product now in development or undergoing evaluation. Post the datasheets of tssp6p38, apraprand pic16fa.


The input preamplifier, AGC, and main amplifier circuits are disabled during playback. Am a ok with coding but need help with some concepts.
