Part Number: OPA838 Dear all,
I have used OPA838 to design an transimpedance amplifier. This design will be used as to convert the output current of an ultrasonic transducer to voltage, the schematic is as follow:
As it is clear form the the bode and…
Hi Michael,
The excerpt highlighted in the design document referencing the performance upgrade is based on the OPA838's higher gain-bandwidth product and lower input voltage noise compared to the OPA836. A table that highlights the performance difference…

Part Number: OPA838 Other Parts Discussed in Thread: OPA356-Q1 , OPA607 Team,
OPA838 has minimum supply voltage of 2.7V.
Can it be operated below 2.7V supply voltage? (With reduced function, if applicable.) What happens if the supply voltage gets below…
Part Number: OPA838 Other Parts Discussed in Thread: LMH6642 Hi Sir,
My customer want to replacei AD8051 by using OPA838. They test OPA838 but find crosstalk at input side. Is that normal at OPA838? Or is there any other OP can replace AD8051 without…
Part Number: OPA838
HI,
I'm finding a opamp with rail-to-rail input/ouput and Unity-gain stable with similar bandwidth to LT6230IS6-10. The cross reference of TI recommend OPA838, but it's decompensated. So are there any other parts from TI? …

Hello Team,
my customer has designed the following TIA and observe an non linear temp. drift issue:
The supply voltage of the OPA838 is 0V and 3.3V, the VREF_OFFSET is 1.45V, so that we can…
Part Number: OPA838 Hello everyone,
I am trying to simulate the OPA838 in LT-SPICE. I had followed the procedure described here:

Thanks for the insight and orientation Kai. I have gone through and removed all of the filters, which required some pretty fancy soldering of jumpers for the 0603 capacitors... I have to pat myself on the back for that :)..
I would say my overall assessment…
Part Number: OPA838 Hello,
I work in a secured network.
My work requires a lengthy vetting process for software to be brought across the gap.
The TI simulator is not part of the approved software instances.
I would like a stand alone pspice model for…
