Part Number: OPA2141 Other Parts Discussed in Thread: OPA2197 , , OPA197 , OPA2140 Hello everyone,
We noticed an unexpected behavior when using OPA2141 as a replacement for a OPA2197 in a simple follower stage of a circuit. I did a simple simulation using…

Part Number: OPA2197 Other Parts Discussed in Thread: OPA197 , PSPICE-FOR-TI I downloaded the PSpice model of opa2197 from the TI website and performed the simulation.
I talked about the symptom that the tool version 17.2 shuts down when you run the newly…
Part Number: OPA2197 Other Parts Discussed in Thread: OPA197 Hi team,
My customer would like to know unused pin termination of OPA2197.
they only use single channel.
then could you tell me how to configure unused IN+/- and OUT pin?
I know single channel…

Part Number: OPA2197 Other Parts Discussed in Thread: OPA197 I'm using an OPA2197IDGKT op-amp powered at 5V. The configuration is a unity gain buffer with the non-inverting input pulled up to 5V with a 5 megohm resistor. This input is connected to a…
Part Number: OPA2197 Other Parts Discussed in Thread: MSP430F6726A , TINA-TI , OPA197 Hi
The OPA2197 is operated with both ± 6V power supplies.
At this time, the -6V power supply contains ripple noise of about 10KHz,
so I inserted a 680Ω and 1μF…
Part Number: OPA2197 Hi team,
Could you please provide a non-inverting amplifier reference design via OPA2197 ? the requirement is shown below:
1. Gain: 10V/V
2. it is used to enlarge the signal of 1VPP whose frequency is 1Mhz.
Best Regards

Hi, Louis,
Our photomultiplier output range is 0-100uA and uses a bipolar ±5V supply. We will consider using the OPA2197 in our next design.
Regarding VCM, we chose to connect it to GND and refer to Figure 8-5 for the design.
Thank you,
Xander …
