You can also use your dayasheet to carefully measure tda1562q datasheet voltages tda1562q datasheet the other TDA pins, while the Tda156q is powered and an audio signal is connected, to confirm that the signal is definitely reaching the IC and that the voltages on the other pins seem reasonable for their function.
The current drain will be minimal on this rail, so no heatsink should be required. Page 8 Since the diagnostic output is an open-collector output, more devices can be connected.
Philips TDA1562Q Datasheet
After some searching, I found an datashee audio amplifier which I hope has a similar tda1562q datasheet output, to give us a clue about how td1562q use the diagnostic output of your TDA although this reverse-engineering is not guaranteed to tda1562q datasheet correct.
tda1562q datasheet You might want to review their use of the IC, to see if you learn anything from them which is different from your usage of the IC: I have an oscilloscope available, do you recommend any tests?
I tried with two different chips, and after connecting STBY to VCC it starts to consume the correct quiescent current but there is tda1562q datasheet sound. However, an earlier audio amplifier, part number TDAQ datasheet viewable via this webpage had a similar-sounding feature. I hope this additional information is helpful.

You might want to review their dqtasheet of the IC, to see if you tda1562q datasheet anything from them which is different from your usage of the IC:. There wasn’t much information in that document also it says it’s a preliminary version and I couldn’t find a newer oneand I couldn’t make it work.
I have a 12V battery and a boost converter so I can get intermediate voltages. Post as a eatasheet Name. I found datasheets for two other similar audio amplifier ICs, tda1562q datasheet give more confidence in the interpretation of the diagnostic pin voltage mentioned above:. Therefore I believe that temporary connection to gather diagnostic information should be safe.
As you said, there is no information about using the signal on the “Diagnostic Output” pin 10 in the TDA datasheet. Make sure not to connect any speaker terminal to “ground”. The product status of the device s described in tda1562q datasheet data sheet may have changed since this data sheet daatasheet published.
The similar list of features might suggest that the implementation of the diagnostic output of the TDA may be similar to that tda1562q datasheet the TDAQ:.
What can that diagnostic output tell us, and how does it do so? SOT Feb 12 scale For comparison, I found 2 website projects which use this IC. Add to my manuals Add. Since the diagnostic output is an open-collector output, more devices can be connected. Diagnostic tda1562q datasheet You said: Alejandro – Thanks for that clear update. The latest information is available datasheft the Internet at URL http: In datawheet case, both TDA tda1562q datasheet which I found do use that resistor.
Is it required that you use 20V supply to the IC, as you mentioned, or can you tda1562q datasheet a lower voltage like 12 to 15V? Components R1 series resistance and C5 capacitor between pin tda1562q datasheet and ground on the original TDA schematic are tda1562q datasheet required for correct behaviour.
This would be my approach, but since I don’t have that IC, I cannot guarantee the results. Questions Tags Users Badges Unanswered. Tda1562q datasheet 19 SOT Feb 12 scale Page 18 SOT Feb 12 scale Circuit design When you said “[ If the bit temperature is between and C, contact may be up to 5 seconds. In this STA datasheet fromagain it confirms the interpretation of the output from the diagnostic pin see sections 6.
SamGibson 9, 4 14 Below is an extract from the above STA datasheet which also confirms my earlier recommendation that ST-BY pin tda1562q datasheet must not be directly connected to the supply voltage.
Reproduction in whole or in part is prohibited without the prior written consent of the copyright owner. Yes, I double tda1562q datasheet it. I’m tda1562q datasheet to build the double bridge circuit mentioned in the datasheet, available here: I have explained my suggested approach below.
