DEM-OPA-SOT-1A: Pin 5 & 6 Orientation

DEM-OPA-SOT-1A: DEM-OPA-SOT-1A

Part Number: DEM-OPA-SOT-1A
Other Parts Discussed in Thread: THS4121

Hi team,

My customer would like to use DEM-OPA-SOT-1A EVM boar to evaluate OPA300AIDBVT and OPA657NB/250.

Could you please clarify the package in which feedback resistor and optional capacitor i.e. R6 and C6 are required on DEM-OPA-SOT-1A?

Another op amp that my customer would like to consider evaluating is THS4121D but he gather evaluation boards with this op amp have been obsoleted. Could you please clarify any other evaluation board which he can use for making a charge amplifier using THS4121?

Thank you very much.

    Hello Yanni,

    I'm not sure I understand your first question, the values of R6 & C6 are dependent upon your device and application rather than the board itself. 

    The THS4121 does seem to be no longer be available. Here is a link to a generic EVM that should work for the SOIC package:

    Best,
