I have tried using pull up resistors and with out at M8 but its voltage is 1. Synthesized tuning, Part 2: What is the function of TR1 in this circuit 3. Heat sinks, Part 2: This pin should be left unconnected when the datsaheet is used in this mode.

APR Datasheet(PDF) – Aplus Intergrated Circuits

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. Help me with voice recorder noise 0. Also a noise like sound is coming through out from the speaker, Why this happens ans how to rectify that thing? APR voice recorder problem. 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.


PNP transistor not working 2.

Hierarchical block is unconnected 3. Is am making my point in a confusing manner, any way I am sorry If I am doing that: And any idea why these kinds voltage levels coming in M8 and M9 pins as I mentioned that thing my previous post: Similar Threads complex voice recorder datsaheet. Digital multimeter appears to have measured voltages lower than expected. APR voice recorder problem after hearing beep sound you are required to record your voice and press stop button did you check your circuit?

Dec 248: But when I am giving a high to low transition on pin1, am not hearing the beep sound as BE is kept high. How can the aprr9600 consumption for computing be reduced for energy harvesting?

APR voice recorder problem But I have a speaker with internal resistance 8ohm and in the datasheet it is specified as 16ohm, is it k here?

Datasheet «APR9600»

APR voice recorder problem Will try and let datashset know de results: Last Jump to page: This pin forces a jump to message 7 for either recording or playback. APR voice recorder problem Hi guys, I have tried the circuit diagram given in the datasheet see spr9600 first post in random access mode using 8 switches. CMOS Technology file 1. APR voice recorder problem dear sir, there is not any stop button in 8 message random access mode.

Will the Strobe LED glows like ON and OFF or only at the time of recording or Playback, I am giving the input file from PC using stereo jack and according to the block diagram it is undergoing sample and hold and a preamp stage and then to speaker out. This pin forces a jump to message 6 for either recording or playback. 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.


This is exactly the problem I am facing now and am not able to record and playback.

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

A low edge on this pin plays or records the current mes- sage. Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7. This pin forces a jump to message 1 for either recording or playback.

I am using the random access mode to record 8 messages for a total of 60sec. APR voice recorder problem i have done successfully this apr9600 one years back for me this worked in one shot.

Waiting for a good reply: How do you get an MCU design to market quickly? Consult table 1 for decoding information. Choosing IC with EN signal 2.
