Part Number: LM1875 I built the circuit as per data-sheet guidelines/values (enclosed pdf file). On feeding an input, I get the output as desired, but the amp shuts down for a few seconds after being in operation for half a minute or so and then again…
Hi Kai,
Using the open loop response curve in the LM1875 datasheet (which other TI engineers have claimed is quite similar to the LM675), I tampered with an existing LM1875 model to produce a phase/gain profile more like the graph shown in the LM1875…
Other Parts Discussed in Thread: LM1875 I am looking at replacing a power amplifier from STMicro that is obsolete, the TDA2003A. The TI LM1875 looks like a potential candidate as it is in the same package and pin compatible. One goal is to minimize other…
Other Parts Discussed in Thread: LM1875 Hi, I have to replace the ST's TDA2030 in an automotive application for obsolescence of the component. I've successful tested the pin-to-pin compatible TI's LM1874, but I need to know the really operative temperature…
Other Parts Discussed in Thread: LM1875 , TPA3106D1 Hi there,
We are looking for a newer device to the LM1875.
I think we are trying to get around 25 Watts of audio power. I believe our LM1875 is currently drawing about 50W and losing about half of that…
The data sheet shows values of the resistors to be 10x (200k, 10k) that of the the values (20k,1k) with dual rail power supply. What is the reasoning behind this?
Thanks, John
Part Number: LM675 Other Parts Discussed in Thread: LM1875 Hi, I have the circuit below. 1 inverting amp and 1 non inverting:
The circuit works fine when no load (or large R loads) are connected. However, when I connect a 16 ohm high power resistor the…
Other Parts Discussed in Thread: LM1875 Hi, I have a query on the ϴj-c value for the LM1875 Audio amplifier in the TO-220 package.
I read on the datasheet that ϴj-c is 3°K/W. That's ok, but.....
on other devices also packaged in TO-220, the ϴj…
Other Parts Discussed in Thread: LM1875 , LM675 Is it possible to use the LM1875 as a power op amp? My requirement would be +/-10v/1 a. into 4-8 ohms from 1khz down to very low freq. and maybe DC. Power supply would be +/- 15v. I see no mention of this…
