*FSO refers to full-scale output under the conditions: VSENSE = 100mV, VRS+ = +25V, or VIN = 1V.
Note 1: All devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by design.
Note 2: Guaranteed by power-supply rejection test.
Note 3: Guaranteed by output voltage error tests (IOUT).
Note 4: Guaranteed by output voltage error tests (IOUT or POUT, or both).
Note 5: IN Input Voltage Range (MAX421_D/E/F) and VRS+ Input Voltage Range (MAX421_A/B/C) are guaranteed by design
(GBD) and not production tested. See Multiplier Transfer Characteristics graphs in the Typical Operating Characteristics.
Note 6: This test does not apply to the low gain options, MAX421_A/D, because OUT is clamped at approximately 4V.
Note 7: The device does not experience phase reversal when overdriven.
Note 8: VPULLUP is defined as an externally applied voltage through a resistor, RPULLUP, to pull up the comparator output.
Note 9: POUT gain accuracy is the sum of gain error and multiplier nonlinearity.
Note 10: Total output voltage error is the sum of gain and offset voltage errors.
Note 11: POUT Output Offset Voltage is the sum of offset and multiplier feedthrough.
