2024年9月22日 · 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.

2009年11月20日 · 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.

2017年9月3日 · 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.

2022年5月27日 · 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.

2020年11月28日 · 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.

2017年10月12日 · 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.

2021年3月8日 · 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.

2018年3月13日 · EDIT: The PNP transistor is used to drive the speaker with the negative half of the signal, but since you don't have a negative supply it's not used in this case. BTW the second circuit shown is no better and the pinout is incorrect. The output of the TLC272 should be pin1 not pin6 and + supply is pin8 not pin7. SG

2009年5月11日 · Here is almost the same schematic from the datasheet of the TLC272, a cmos opamp. Greetings, Bertus ...

2012年1月7日 · I want a rail to rail op-amp that use single supply so that I can bais it somewhere at 2.5V and still get 0 to 5V using a battery. I have found a couple of op-amps, which are: TLC272, LT1466, LM324N, TLV2771, LM6144. What could be the best choice, or is there anything else that you suggest? Thanks
