Part Number: OPA37 Tool/software: My question is simple. What do I do if the Trimming pins 8 and 1 are not use for my application ? I could not find any information about it in the specification/data sheet. Thanks. Donald.
Part Number: OPA37 Tool/software: I need to simulate the charge circuit. That's a charge control circuit series connecting a cap.
But I can't simulate normally. Vshunt node keep sinking currnet through R9、R7、R13 to the ground
So the OPAs can't work…
Part Number: OPA37 Other Parts Discussed in Thread: OPA4227 , OPA4228 Hi TI expert
Please help to find a 4 channel amp and similar with OPA37.
Best regards,

Part Number: OPA37 I am looking to design a transimpedance amplifier for use in a pulse oximeter, I'd like to design not only for feedback resistor but also for the feedback capacitor but for this I need to know the differential input impedance, it is…
Other Parts Discussed in Thread: OPA37 , OPA27 I need a hydrophone preamplifier circuit with frequency response in the range of 2Hz to 30 Khz with single voltage supply. The data sheet of OPA37 contains a hydrophone preamp for EDO6166 transducer with…
Other Parts Discussed in Thread: OPA37 , OPA227 , OPA27 Hello,
I have designed an active filter using a OPA37 as shown below, but it causes oscillation at the output near 400Mhz frequency. I have tried increasing the feedback resistance t further increase…
Hello sir,
I attached the solder mask file in the attachment. Kindly see and suggest any correction if any. In this file U3, U4, U17 and U19 are the OA2111 and rest are OPA37.
Hello Pei,
Michael brings up valid points about the phase margin that needs to be assessed and assured when attempting to apply an undercompensated Op amp such as the OPA37 in a TIA application circuit. I suspect there is a stability issue with one…
Hello Rhandhir,
Unfortunately, the original 2012 e2e post wasn't specific regarding the location of that file. The e2e PDF access may have worked differently then, compared to today and that may be the reason it is no longer accessible. I receive the…
