      Noise vs. input common mode
      Discussion

      In Figure 31 of the datasheet, I assume the test was done with input at mid-scale, in this case ground. Is the noise degraded if the input common mode is at the negative rail?

        Using ADHV4702 with asymetrical negative supply lower than -175V
        Discussion

        Hello, I have to use the adhv4702-1 with +10 -200V power supplies, so with VEE too low for a DGND pin tied to ground. All examples are about positive shift of DGND. I cite page 30 of the datasheet : "For applications that require a positive asymmetrical...
