Albert,
The OPA37 is a so-called decompensated op amp, intended for operation in gains of 5 or greater. It may appear that the resistor ratios put the op amp in sufficient gain for stable operation, but his is not the case. The feedback capacitor, C2…

There are a number of things that can cause the output to be influenced by the ambient air-- as you said "Air Con Off". One is simply the thermoelectric potentials caused by dissimilar metals in the input portion of your circuit. Very high…
Other Parts Discussed in Thread: OPA177 , OPA27 , OPA277 Iam using Op-amp opa177 for the samll signal amplification purpose. In op-amp opa177 pin no.1 & 8 are used for offset trim. but if I do not want to trim the offset So where should I connect these…
Other Parts Discussed in Thread: ADS1258 , OPA27 , OPA2727 Hi friends.
We already used the ADS1258 on other projects with great results, but the circunstances now are different.
We are using the ADS1258 on a project to acquire bipolar signals, ranging…
Other Parts Discussed in Thread: OPA4131 , TINA-TI , OPA131 , OPA27 Hey,
I'm now working on a trans impedance circuit using OPA4131(please see the following schematic), the bandwidth is set pretty low @ 330Hz, but the circuit oscillates (~3MHz) with…

This may help. It is an old (2000) presentation that I made to the Burr-Brown Field Applications Engineers (pre-TI acquisition) about using op amps as comparators.
It contains bench test data on op amps that were popular at that time…
Thomas;
This question comes up now and then, so a long time ago I created a PowerPoint presentation for our Burr-Brown field applications engineers about using op amps as comparators. You may be interested in the test data, so I'll attach it.
Op…
Dear Customer,
The INA117KU uses the standard TI leadframe, Cu alloy base with NiPdAu plating finish. Tin finish has not been used on this device for many years.
Lead finish is clearly defined in the product datasheet, addendum page 1.

Part Number: UAF42 Other Parts Discussed in Thread: LMC7660 Hello,
I have designed a band pass filter using part UAF42AP at f = 500 HZ (See my circuit schematics at 1.tiff). The filter is working well and neutralizing unwanted signals at other frequencies…
