Part Number: OPA2137
Hi,
I am using OPA2137 in a non inverting configuration. I have 10Koham in the negative input and 100Koham in the feedback for 11X amplification. I am using +9V and -9V batteries to power the amplifier. In order to test the setup…
User,
If the circuit is wired as you drew it out, then removing ground connection to OPA2137 board would change amplifier gain from 11 down to 1.
When it doubt measure it out. Check the voltage on pins 1-4, 8 to see the whole picture.
Correct would…
Hey Rick,
If you check JEDEC spec MO-187, it specifies in the title that this is the spec for "0.65 AND 0.50 Pitch". I have linked TI's package page below, the JEDEC spec that covers the VSSOP package, and TI's package drawing for VSSOP (DGK) that corresponds…
Hello Venky,
Here are some parts you may consider. They have similar or better bandwidth, maximum voltage offset, slew rate, supply current, and voltage noise specifications as the LF442CN. They are also +/-18V supply capable, like the LF442CN, and…
Hi Prasad,
JC's suggestion is exactly right. If you set the gain of your sources VCVS3 and VCVS1 to 0.5 (500m), you can use post-processing to extract the CMRR without seeing the divide by zero issue. In this case the CMRR of the OPA2137 model is equal…
Tomoaki, I believe you mean to compare EMC performance of OPA2333-Q1 to OPA2317-Q1 and NOT OPA2137 - last one is a completely different part. Since OPA2317-Q1 is a low cost version of OPA2333-Q1 and they both are based on the same physical chip, their…
Hi carla,
No problem, we are always glad to help you
So the datasheet of opa2137 mentions common mode input stage as( V-)+3 V to V+
V+ here means the vcc or the positive supply you have connected to the op amp
For example
If say op amp is connected…
