• ADA4637-1 and OP37 pin compatibility in SOIC

    Are ADA4637-1 and OP37GSZ in SOIC package pin compatible?

     

    ADA4637-1 and OP37GSZ, are not pin compatible. But if you can externally short
    pin 5 and 8, then they become pin compatible.
  • Composite amplifier using ADA4637-1 and ADA4870-1

    I want to build a composite amplifier using the Figure 77 of the datasheet ADA4870-1. It says that the voltage offset is less than 500 uV. I simulate this circuit using LTSpice, when driving ada4637-1 with 0V and monitor the output of ADA4870-1, it is…

  • ADA4627-1 and ADA4637-1 Null Inputs Connection

    Hi,

    ADA4627-1 and ADA4637-1 have NULL pins which are offset adjust pins. If I do not plan to use offset adjust what should I do with the NULL pins? Leave it floating or use 100k Ohm pull-up resistors?
