Sep 22, 2024 · The TLC272 is a dual op-amp, I note the TLC270 is a single channel and looks like a differing 'beast' looking at the data sheet, I'm after a single version of the TLC272, looks like I'm gonna have to try it or use the dual op-amp leaving one side un-used..... something I don't really like doing.

Nov 20, 2009 · The TLC272 is a CMOS operational amplifier that has a common mode input range to the negative rail. Post your schematic as it now exists. You would likely be better off going to a comparator (like a commonly available LM339) and add hysteresis.

Nov 19, 2017 · My jellbean part is the TLC27m2 (When an LM358 won't work). I also use the TLC272 and TLC27L2. Cheap especially the TS272 version.

Sep 3, 2017 · Hello, Have a look at IDD of the TLC27L2 and compare it with of the TLC272. There is a factor of about 100 in the given current.

May 27, 2022 · Just about any "modern" opamp is going to have better specs than the 741 (e.g. wider input and output voltage ranges, faster slew rate, higher GBW), but they'll cost more than a 741 and will likely have a smaller operating voltage range.

Feb 27, 2009 · no I can,t tell anything is getting warm the op-amp says(tlc272) the square wav reads the best and stays consistent but the other two change the triangle wave goes in and out to a out of control waveform and the sine wave stays out of control.

Aug 13, 2014 · I just setup a non-inverting circuit using an tlc272 op amp cp. But I am not sure of what the op amp does. I am using a potentiometer to control the voltage supply. I believe there is suppose to be some type of gain but when check the amount of …

Nov 28, 2020 · I will try your helpful circuit suggestions this evening and report back. Get it working at 16V with the 8V offset and then see if I can reduce it a bit. I assume the LM324 specified in your diagram is just SPICE a placeholder for the TLC272. The output of your simulation is exactly what I am looking for. I noticed a mistake in my diagram.

Oct 12, 2017 · hi, so i am trying to make a current limiting lower supply but im having issues with the current limiting portion. what i am using to measure the current is a TLC272/LM358 (I've tried both) op amp differential amplifier across a 1 ohm resistor and it should output a voltage equal to the current flowing.

Mar 8, 2021 · I'm trying 0 to 10v signal for power level (0 to 100%) not using any potentiometer only with microcontroller (arduino,atmega) gives signal and further 50% signal then 5v output produced. I'm also trying with Opamp and X9C103s IC vw and vh but wiper not set please suggest me any solution.
