APR datasheet & applicatoin notes – Datasheet Archive
I am doing a mini project on voice guider for old people using apr ,,i am tryng to record voice using microphone in apr ,but the busy pin led always glows and there is no beep sound from the speaker when we try to start recording,,what should i do?? Use apr ICit is a voice recording IC and also playback. It is ideal for portable voice recorders, toys, and many. Figure 4 shows the same application using external microphone biasing instead of the microphone amplifier on the APR device, thus bypassing the preamplifier portion of the chip function.
These specifications represent a stress rating only. But i am not geeting response wi.
No recording or playback is allowed. In apryou may record maximum of 60 seconds and playit back datashedt different settings through the Buttons connected. Except pins 23 and 27 which have internal pull-up resistors. Operation of the device at maximum conditions for extended periods may affect reliability.
When pins are connected as shown in this example,the operating modes datasehet as follows: The A version is recommended for 5V designs and the B version More information. History Issue Date Remark 0. B No part of this document may be reproduced, stored in a retrieval system, or transmitted in any form or by any means, mechanical.
Table 2 Absolute Maximum Ratings. Copy your embed code and put on your site: Features Supports both constant voltage and constant current drive mode Constant output current range mA 5V supply voltage mA 3. The display level range is 9mVrms to mVrms Typ.

Low Injection Power for crystal. It provides high-quality recording datasyeet playback with a single to second message. It is designed to be used as a building block in other projects where a.
Automatic power-down feature for longer battery life. Total Harmonic Distortion Note 1: Interface it with the Am a ok with coding but need help with some concepts. It includes a current shunt comparator and shutdown comparator.
APR9301 RE-RECORDING VOICE IC
The typical sampling frequency is 6. The package is -pin lead-less minimold, suitable More information.
Die diagram is with respect to die center um Die Dimensions: If any one of you has previously worked on it, please give me hint or code if. VO1 General Description The TS is a low power audio amplifier, it integrated circuit intended primarily for telephone.
The typical sampling frequency is 6. Start display at page:. Least external components, More information.
Internal functions More information. Single Operational Amplifier www.
Description The 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. Messages of up to 30 seconds can be recorded by using different OscR resistor values see Table 1. The APR device stores and reproduces voice signals in their natural forms. Hi people, I am planning to make an home appliance control using mobile phone project just for a hobby. Current consumption is typically less than 1uA.
For the apr i have folllowed the circuit as in datasheet for random access mode but i am going to control this with the help of microcontroller. In the voice chip datasheet example circuits are given. C monolithic integrated circuit.
