Input Common Mode Range of THS4131 in Single 5V Operation

Other Parts Discussed in Thread: THS4131, OPA1632, ADS1271

To drive ADS1271, I use OPA1632. But OPA1632 consumes too much power. I find THS4131 has similiar input voltage noise performance and it can operate at single 5V. So I'd like to shrink my power rail from +/-15V to single 5V and take THS4131 as a replacement of OPA1632.

My question is, in single 5V operation, what is the input common mode voltage range? I cannot find the parameter in the datasheet. The one there is for +/-5V.

    Hello Yang,

    In the +-5V table it shows that the input common mode range is -4V to +4.5V.  From this you can calculate that the input common mode range would be 1V from the negative power supply rail and 0.5V from the positive supply rail.  In your case it would be from 1V to 4.5V.
