• 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?

    Regards,

    Ivan.

  • ADA4870 - composite amplifier


    Hi,

    I am trying to make a project based od ADA4870 figured as unity gain current buffer. Looking on it's 23th page of datasheet i found it connected with composite amplifier and i have some questions now:

    1. Is the ADA4637-1 absolutely best amplifier…

  • RE: LTC6090/LTC6091 as High Voltage buffer front end for SAR ADC

    Tony,

      I like to get the signal out of the noise and then divide.

    You have another problem:  The ADA4637 is only stable with a noise gain greater than five.

  • RE: Over voltage protection input of AD8610?

    Hi, wivern.

    AD8610 is only specified to operate in a maximum supply voltage of ±13V. Above that, the part will be damaged. If you need ADI part with more than ±13V supply, then you may use ADA4627-1/ADA4637-1 which can go as high as ±18V.

    As to the…

  • RE: Pspice model for LT6275

    Could you check ADA4637? drawback is not so low power, 7mA supply current compared to almost 2mA for LT6275.

    G=10 is flat at 1MHz, supply voltage is up to 30V and output voltage is 25Vpp typical.

    Slew rate is quite high at 170V/us but not on the range…
