Note 1: All devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by product
characterization.
Note 2: Extrapolated to VOUT = 0. ICC is the total current into the RS+ and the RS- pins.
Note 3: Input offset voltage VOS is extrapolated from a VOUT+ measurement with VSENSE set to +1mV and a VOUT- measurement
with VSENSE set to -1mV; vis-a-viz,

Note 4: Amplitude of VSENSE lower or higher than VOS required to cause the comparator to switch output states.
Note 5: Gain error applies to current flow in either direction and is calculated by applying two values for VSENSE and then
calculating the error of the actual slope vs. the ideal transfer characteristic:
For GAIN = 25, the applied VSENSE is 20mV and 120mV.
For GAIN = 50, the applied VSENSE is 10mV and 60mV.
For GAIN = 100, the applied VSENSE is 5mV and 30mV.
For GAIN = 200, the applied VSENSE is 2.5mV and 15mV.
Note 6: The device is stable for any capacitive load at VOUT
.
Note 7: VOH is the voltage from VRS- to VOUT with VSENSE = 3.6V/GAIN.
