About ADA4350

Hi

I have a question ADA4350.

I using S0,S1,S2. no using S3,S4,S5.

6pin FB3,5pin FB4,4pin FB5 and 1pin SWB OUT is connect to GND .it is no problem?

And ,

When using ADA4350 and ADC, Is it no problem to change using chip select?

Best Regards

HOD

    Hi, HOD.

    There will be no problem if you connect pins 6 (FRB3), 5 (FB4), 4 (FB3) and 1 (SWB_OUT) to ground. These pins can also be left floating because these are not internally connected to the FET Amp. Please take note that leaving these pins unused, some bits in serial mode and parallel/manual mode operations should also be unused. Please see pages 28 and 29 of the datasheet for the bit map.

    Using the pin 23 (chip select in serial mode) with the ADC is no problem. Please refer to pages 13 and 14 of the datasheet for the timing specs and diagram.

    Hope this answers your questions.

    Thanks,

    Anna
