Other Parts Discussed in Thread: TLC2274 , OPA4171 , LM2901 Dear all
Now one of my customer is using our TLC2274, and find two misbehavior for the TLC2274.
TLC2274 cannot supply enough load. Here below is the basic test circuit, when the input is 3.3V(DC…
Other Parts Discussed in Thread: TLC2274 Dear all,
for my master thesis project I am designing a photodiode readout circuit. I use the TLC2274 opamp as a transimpedance amplifier with a gain of 680kOhm and the photodiode is in zero bias. The power is supplied…
Part Number: OPA4192 Other Parts Discussed in Thread: TLC2274 , , OPA2192 , OPA192 HI, I am going to use OPA4192 as voltage follower, buffer circuit. I used TLC2274 before.
.
I will connect
IN + : ADC Input
IN- : Connect to OUTPUT.
.
And here is my question…
Looking at the date of this post I wasn't sure if I needed to reply. I trust you've resolved the issue by now, but if not please change the summing amplifier gain to 1 and remove the divider on the output of the 1.5V offset. I also removed the…
Hi,
I have modeled the TLC amplifier as in DMC1500 schematics. However I am unable to get the proper output values in simulation for various current ratings. The output matches for -30A, 0A and +30A (at limits only), for other current values the results…
Part Number: TLC2262 Other Parts Discussed in Thread: OPA196 , TLC2274 , TLC2272 , TLC2264 , TLV2371 Hello,
I use a lot of TLC2262/4 in my designs. I find myself needing a SINGLE op amp but there doesn't seem to be one in that family. Is there another…
Part Number: OPA2134 Other Parts Discussed in Thread: TLC2274 , Hi,
can you please look at the attached cirucit diagram. What you think about it.
I believe ist risky because we can have a voltage at the output while no supply voltage is present
Basically…
Hi, Kai.
Thanks for the reply.
Then do you think TINA-TI simulation result could be incorrect to the LM324? How about the LMV324? Do you think the LMV324 could also have same problem in terms of the voltage offset drift, and should I take the precision…
Hello Hal,
I suspect you are asking about the TLC2274 CMOS operational amplifiers.
It does not have reverse polarity protection. That is not a commom feature for analog integrated circuits. I know of only one TI operational amplifier family that does, the…
Hi Bryan,
I was able to replicate your results using the TLC2264.101 model downloaded from the TLC2264 product page (687uA output current, clipping at 6.5V). When using the TLC2264.102 file, however, I was able to get about 1.1mA at the output before…
