Part Number: TLC2254 The title says it all. The very best precision bipolar amps specify around 100nV/month; 3nV/month is better than (the spec) for many chopper/autozero amps It appears to me to be another example of an erroneous result from applying…
Part Number: TLC2254 Other Parts Discussed in Thread: OPA188 Hi,
The TLC2254 doesn't output the popcorn noise because it is manufactured by CMOS process.
Is it correct?
Best Regards,

Hello TQ,
Sorry for the delayed response.
Yes, the noise reported here is a typical specification and likely represents one standard deviation. It is usually determined by measuring a number of devices during original characterization of the device…
Part Number: OPA4277 Other Parts Discussed in Thread: TLC2254 , TL064 , OPA4132 , OPA4188 Hi, support team
My customer has the questions as follow:
The supply voltage is ±5V. Input voltage is 3V pulse signal, duration of high level is 1.6ms and the…

I have a question about how the TLC2264 and the TLC2254 compare. I'm using the precision amp as a buffer amp to the input stage of a 12-bit ADC. I closely examined the datasheet for both devices…
Hi Jeff,
I've added comments to your discussion :
The concern is that the circuit we have been using has VDD+ at 12V and VDD- at 0V (GND). This differential is within the 16V differential spec, but of course, the input voltage level is being violated…
Hi Randy,
Sorry we have been a little slow getting back to you. Many people were away for the Thanksgiving week. I'll will try to assist you with your first question.
When I look at your requirements for the operational-amplifiers used in the i…
Hi Randy,
EMI could possibly be the issue. It is interesting that you see the correlation between RF transmission and the low frequency noise. Do you know where in the signal chain you are first seeing the noise and would you be able to capture an oscilloscope…
