Dear Team,
I am Rohit Gupta, a Hardware Designer at Applied Electro Magnetics Pvt. Ltd.
We are using the OPA2187 operational amplifier in one of our projects. As part of our customer documentation, we need to specify the…
Part Number: OPA2187 Tool/software: Hi team,
I have a question regarding the input voltage range of the OPA2187. On page 7 of the datasheet, under “INPUT VOLTAGE RANGE,” the VCM (common-mode voltage) maximum is listed as (V+) - 2 . Is this correct?…
Part Number: OPA2187 Hi Team,
I’m Rohit Gupta, a hardware designer at Applied Electro Magnetics Pvt. Ltd.
I am currently working on a circuit that includes an op-amp configuration, and I’m finding it challenging to analyze its output accurately through…
Part Number: OPA2187 Tool/software: Could you confirm the below question for OPA2187?
Regarding the input bias current of the OPA2187, do both amplifiers (from the IC's perspective) flow in the same direction? Or does the direction change randomly…
Part Number: OPA2187 Dear Specialists,
My customer is evaluating OPA2187 and has a question regarding offset voltage vs Vcm.
The offset voltage varies non-linealy with input common mode voltage.(within the spec <15uV)
I would be grateful if you…
Part Number: OPA2187 Other Parts Discussed in Thread: ALM2402F-Q1 , ALM2402-Q1 , ALM2403-Q1 Tool/software: In the datasheet, it says that the output can be shorted to ground continuously. Can it also be shorted to the power supply? (Obviously not at the…
Part Number: OPA2187 Other Parts Discussed in Thread: RES60A-Q1 Tool/software: Hi,
Greetings!
I’m Rohit Gupta, a Hardware Design Engineer at Applied Electro Magnetics Pvt. Ltd. We are currently using the OPA2187 operational amplifier for high-side…
Part Number: OPA2187 Tool/software: The output of some amplifiers changes by about 1.4 mV at temperatures between 20 and 30 degrees Celsius.
During testing, the operation changed when the resistance of the op-amp was changed to 200 kΩ, 820 kΩ, and 51…
Part Number: OPA2187 Tool/software: Hi,
AOs like OPAx187 using auto zeroing techniques, provide low offset and near zero drift over time as indicated in the datasheet.
Could you provide some data/figure for the offset voltage drift over time?
B…
