APR Datasheet(PDF) – Aplus Intergrated Circuits

It encodes data and address pins into a serial coded waveform suitable. In the voice chip datasheet example circuits are given. Design a broadband amplifier using a bipolar NPN transistor in a common emitter orientation. It is designed to be used as a building block in other projects where a More information.

Even though it seems to be simple to write the code datasehet reference to datasheet i am not able to record or daasheet the voice.

It is capable of 18 functions and a total of 75 commands. It includes a current shunt comparator and shutdown comparator More information. It is ideal for portable voice recorders, toys, and many. The APR device stores and reproduces voice signals in their natural forms. Except pins 23 and 27 which have internal pull-up resistors.

The STKV series use the. B No part of this document may be reproduced, stored in a retrieval system, or transmitted in any form or by any means, mechanical.

Description The itf is a;r9301 ultra-wideband phase delay with an ECL topology to ensure high-speed operation that accepts either single-ended or differential data input.

Copy your embed code and put on your site: What part of circuit are you having problem? The gain is internally set to 20 to keep external part count. Messages of up to 30 seconds can be recorded by using different OscR resistor values see Table 1. Interface it with the If the newly recorded message is shorter than the previously recorded message, the remaining portion of the previous message datashewt not be played after the new message is played back. Placement Features More information.

Internal functions More information. Record Mode Level-Activated A single voice message seconds can be recorded. These specifications represent a stress rating only. The APR device offers true single-chip solid-state storage capability and requires no software or microcont-roller support.
