Note 9:
All devices are 100% production tested at T A = +25 ° C. All temperature limits are guaranteed by design.
Guaranteed by power-supply rejection test.
Guaranteed by output voltage error tests (IOUT).
Guaranteed by output voltage error tests (IOUT or POUT, or both).
IN Input Voltage Range (MAX421_D/E/F) and V RS+ 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 .
This test does not apply to the low gain options, MAX421_A/D, because OUT is clamped at approximately 4V.
The device does not experience phase reversal when overdriven.
V PULLUP is defined as an externally applied voltage through a resistor, R PULLUP , to pull up the comparator output.
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.
