Such measures include but are not limited to protective circuits and error prevention circuits for safe design, redundant design, and structural design.
1 To 2.2W Typical Single-chip Audio System For Tape Recorders
I’m not planning to make “professional” recordings on the tape recorder that will emerge at the end of the project. Email Required, but never shown. Given the rest of the Datasheet, I might be able to locate the point where this oscillator has to go. Specifications and information herein are subject to change without notice. Preamplifier The preamplifier circuit consists of the input differential stage TR9, 10daasheet shift stage TR13and output stage TR17, 18, Now, the oscillator needs to be a sine wave, but that’s pretty much all I know.

It means you need a separate bias generator anyway.

Shouldn’t the chip provide the bias current, etc? Upon using the technical information or products described herein, neither warranty nor license shall be granted. Sign up using Facebook.

The head’s resistance vatasheet primarily inductive at such frequencies, so it makes the AC bias voltage many times higher than the recording voltage or even the amplifier’s supply voltage.
The products mentioned herein shall not be.
To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and daatasheet devices mounted in the customer ‘ s products or equipment. You may have to use a transformer to couple the two signals together and this still may cause the regular amplifier some issues.

Since the output stage is of push-pull datasneet, no remarkable drop in the output voltage occurs even at. An Example of Printed Board Cu-foiled side.
No part of this publication may be reproduced or transmitted in any form or by any means, electronic or. It’s a microcassette recorder. This catalog provides information as of August, It is possible that these probabilistic failures or. An erasing head is commonly attached to the generator directly, and a secondary winding of the transformer is capacitively coupled to the recording amplifier output. When designing equipment, refer to the “Delivery Specification” for the. I just want a proof of concept type of thing.
If there is no consultation or inquiry before the intended use, our. Consider this circuit of the LA Information including circuit diagrams and circuit parameters herein is for example only; it is not guaranteed for datasheeet production.
It’s likely just a permanent magnet that saturates the magnetic tape in one direction. AC bias circuit for a tape recorder Ask Question. Information including circuit diagrams and circuit parameters herein is for example only; it is not guaranteed.

On the other hand, it may not work because the “simple” resistor circuit above may cause the amplifier producing the regular record signal the audio to clip and distort.
To verify symptoms and states that cannot be evaluated in an independent. Check the type of your recorder erasing head. VG pre 20 log Z1 datashedt. Since the output stage is of push-pull type, no remarkable drop in the output voltage occurs even at low load impedances and the output can be connected direct to the ALC circuit and meter circuit.
You need to know your recording head’s inductance, maximum recording current and maximum bias current to design the bias generator. It is possible that these probabilistic failures or malfunction could give rise dataseet accidents or events that could endanger human lives, trouble that could give rise to smoke or fire, or accidents that could cause damage to other property.
Would be nice if someone could take a look at the datasheet I’ve linked, and maybe point out a thing or two, if I missed something. It looks like the circuit in page 3 will not be able to record anything in acceptable quality, but it can be a mistake in the datasheet itself.
I think somewhere around kHz makes the most sense. It might be no more difficult than making a 70kHz signal and adding it to your “normal” record signal that feeds the tape head. Such measures include but are l4a160. I was thinking maybe there’s an IC for that available, but again, I’m not sure on that one. If you should intend to use our products for applications outside the standard applications of our.
