This pin forces a jump to message 5 for either recording or playback. Also a noise like sound is coming through out from the speaker, Why this happens ans how to rectify that thing?

Single-Chip Voice Recording & Playback Device 60-Second Duration

Home – IC Supply – Link. This pin forces a jump to message 8 for either recording or playback. PV charger battery circuit 4.

And any idea why these kinds voltage levels coming in M8 and M9 pins as I mentioned that thing my previous post: APR voice recorder problem Will try and let you know de results: Thanks so much for the advice. According to the datasheet description, one can neither perform recording or playback at that time.


APR voice recorder problem after hearing beep sound you are required to record datasgeet voice and press stop button did you check your circuit?

Waiting for a good reply: Turn on power triac – proposed circuit analysis 0. This pin forces a jump to message 3 for either recording or playback. APR voice recorder problem i have done successfully this circuit one years back for me this worked in one shot. Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7.


What can be the reason? How reliable is it? The ANA input part is the same that I have connected. But when I am giving a high to low transition on pin1, am not hearing the beep sound as BE is kept high. AF modulator in Transmitter what is the A? Originally Posted by Akhil Mohan.

Why this happens in my case? Same as Mode 1. Distorted Sine output from Transformer 8. datasjeet

This active low input This pin should be left unconnected pin forces a skip to the next message when the device is used in this for either playback or recording mode. Thanks in advance, Akhil.

Last edited by Akhil Mohan; 5th July at A low edge on this pin plays or records the next message. I am using the random access mode to record 8 messages for a aor9600 of 60sec.

APR voice recorder problem as you can see M8 pin has k pull up resistor. When I am connecting the IC to supply the busy LED turns ON and from the datasheet what that signifies is the device is currently busy performing internal functions and can neither record nor playback at the current time.

I am not dtasheet to record the sound file. Equating complex number interms of the other 6. So if am not giving any input signal the speaker out should be zero and during the ON it should varying nature,please correct me if I am wrong. CMOS Adtasheet file 1. I have tried using pull up resistors and with out at M8 but its voltage alr9600 1. This pin indicates that the device is currently busy per- forming internal functions and can neither record nor play- back at the current time.


Synthesized tuning, Part 2: APR voice recorder problem http: Results 1 to 20 of APR voice recorder problem Hi guys, I have tried the circuit diagram given in the datasheet see my first post in random access mode using 8 switches.

During playback dafasheet low level on this pin indicates that all recorded mes- sages have been played.

Suggest me a voice recorder chip 5. This is exactly the problem I am facing now and am not able to record and playback. I think that means my IC ar9600 working properly. Digital multimeter appears to have measured voltages lower than expected. This pin forces a jump to message 6 for either recording or playback. APR voice recorder problem I have done that already, but not hearing any beep sound when there is a high to low transition on pin1.

Santhosh, Send me the circuit when you have time, by the time am also trying to solve the problem. Then set the initial conditions for CE and RE as low for record.

APR voice recorder problem dear sir, there is not any stop button in 8 message random access mode.
