Hi Eli,
The OPA453 is not unity gain stable. It is optimized for closed-loop gains of 5 V/V, and greater. You might have instability problems if you try and use it in your <5 V/V gain circuit. A very similar amplifier, the OPA452, is unity gain stable…
Elizabeth,
The OPA452 has an input common-mode range that must be greater than 5V above the negative power supply terminal. It will not operate properly with a single power supply and input voltage of less than 5V.
We call op amps that can operate…

Hello to all,
Now I intend to apply XTR110 as voltage-controlled current source to a neuromuscular electrical stimulation (NMES) device. Input signal is pulsed biphasic…
Hi,
I was trying to design a driver of a proportional valve. My driver has ±10VDC input and ±100mA output (Load: 200 ohm, 0.5 H, Series RL) I have two supplies which are 28±4VDC and -28±4VDC. I applied this circuit and simulated. I take ±100mA when…
The OPA145 also looks like a good choice, this file has not been recently updated so the OPA196 is not in yet, and the pricing is out of date.

Connecting a capacitor on the output of an op amp can often lead to oscillations instead of the expected response. Also, the amplifier feedback resistors can interact with the amplifier input capacitance causing oscillations. These issues are called op…
to User473,
I searched all the op amp portfolio with the parametric search (precision, general purpose, and high-speed). There are 6 options with temperatures of 150C and above (see attached). The best match is the OPA211-HT (210C max). This is the…
