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…
Other Parts Discussed in Thread: OPA2137 , TL032 , TL062 , TLE2062 Hi,
LF442CN/NPOB Op Amp Dual Low Power Amplifier ±18V 8-Pin PDIP part is used in one of our old design, I'm looking for a Functional form fit replacement.
Please suggest me a replacement…
Part Number: OPA2317-Q1 Other Parts Discussed in Thread: OPA2333-Q1 , OPA2137 , Hi team,
Our customer is looking for low offset and EMC torelance dual opamp, because they are in trouble with the EMC test of the system.
Although they can evaluate only OPA2333…
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…
Other Parts Discussed in Thread: INA217 , OPA2137 Hello,
I'm working on a pre-amplifier using the INA217, but I couldn't get a linear operation for Vout. I saw that I can use this op-amp as single supply, but I can't make that work. Any suggestion?…
Hello Errol,
thanks for your answer. I was using a datasheet from Farnell, which doesn't include this page.
The OPA2137 seems to be an appropriate candidate, though I wished a wider temperature range - would you know another alternative here? The GBW…
I wondered if we might run into the issue of too much noise! For the op amp spots I think the OPA2137 or and OPA2170 might be good options. The OPA2170 is a low power CMOS part thats about 23nV/rtHz at 100Hz and a gain bandwidth of 1.2MHz (you don't mention…
