PDF LA4160 Datasheet ( Hoja de datos )

A single package contaning preamplifier, ALC circuit, power amplifier. Now as you can see in the lower left corner, there is a device “Bias OSC”. It might be as simple as mixing those two signals using resistors. I was thinking maybe there’s an IC for that available, but again, I’m not sure on that one.

It looks like the circuit in page 3 will not be able datasjeet record anything in acceptable quality, but it can be a mistake in the datasheet itself. La41160 verify symptoms and states that cannot be evaluated in an independent.

OK, this is how far I’ve got: You may have to use a transformer to couple the two signals together and this still may cause the regular amplifier some issues. I think somewhere around kHz makes the most sense. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Since the output stage is of push-pull type, no remarkable drop in the output voltage occurs even at. Information including circuit diagrams and circuit parameters herein is for example only; it is not guaranteed.

I don’t know which peak-to-peak level, and I’m not entirely sure what frequency. When designing equipment, adopt safety measures so that these kinds of accidents or events cannot occur.

This is a screenshot of the datasheetpage 4.

audio – AC bias circuit for a tape recorder – Electrical Engineering Stack Exchange

This is just a little project to play around, nothing serious. Anyway, it’s better to replace it with a ferrite erasing head because it demagnetizes the tape and prevents it from producing low-frequency saturation noise. I found some schematics for AC bias circuits, but they were all very different, and I’m not sure which one is suitable for tape recorders. On the other hand, it datasgeet not work because the “simple” resistor circuit above may cause the amplifier producing the regular record signal the audio to clip and distort.

I’d like the most simple solution, which could be easily put on a daughter board and hidden in the tape recorder.

It is possible that these probabilistic failures or. When designing equipment, refer to the “Delivery Specification” for the. It’s a microcassette recorder. Such measures include but are not. LA is Single-chip tape recoder audio system.

Or is it an IC that eludes me? On page 3 of the datasheet, the bias oscillator is missing, is that DC biased then there’s just a filter with unmarked cap and resistor? Sign up using Facebook. The simpliest bias generator circuits contain one transistor, a transformer, and several capacitors and resistors. Email Required, but never shown. It means you need a separate bias generator anyway.

The bottom line is try it and see and if it doesn’t work then no harm done. Sample Application Circuit 2: Sign up or log in Sign up using Google. If you should intend to use our products for applications outside the standard applications of our. An Example of Printed Board Cu-foiled side. VG pre 20 log Z1 dB.

Home Questions Tags Users Unanswered. No part of this publication may be reproduced or transmitted in any form or by any means, electronic or. It’s likely just a permanent magnet that saturates the magnetic tape in one direction. Given the rest of the Datasheet, I might be able to locate the point where this oscillator has to go. Preamplifier The preamplifier circuit consists of the input differential stage TR9, 10level shift stage TR13and output stage TR17, 18, It seems there isn’t too much information out there when it comes to tape circuits.

To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and test devices mounted in the customer ‘ s products or equipment.

Post as a guest Name. It might be no more difficult than making a 70kHz signal and adding it to your “normal” record signal that feeds the tape head. When designing equipment, adopt.

It is possible that these probabilistic failures or malfunction could give rise to accidents or events that could endanger human lives, datashfet that could give rise to smoke or fire, or accidents that could cause damage to other property.
