The feedback resistor for hysteresis on channel A will be the combination of R11 and R13. Both resistors must
be populated. When measuring the INA+ input signal on an oscilloscope, we recommend using a dual channel
function generator so that one of its outputs can be directly connected to the oscilloscope. Ensure that both
signal generator channels are outputting the same signal.

For non-inverting hysteresis on Channel B, the INB+SENSE SMA connection will serve as the input to the
device. The input resistor will be series resistor R8. The feedback resistor for hysteresis on channel B will be
the combination of R9 and R10. Both resistors must be populated. When measuring the INB+ input signal on an
oscilloscope, we recommend following the same recommendations as Channel A.
