Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

All devices are 100% tested at T
A
= +25°C. Limits over temperature are guaranteed by design.
R1 = 215kΩ, R2 = 210kΩ for the MAX4069 only (see
Functional Diagram).
This sets REFOUT to 2.49V nominal.
Guaranteed by the PSRR test.
The REFOUT voltage for the MAX4069 should be set such that it does not exceed V
CC
- 1.1V. Similarly, the maximum REFIN
voltage for the MAX4072 should also be less than V
CC
- 1.1V.
Note 5:
Input-Referred Offset Voltage is defined as the voltage difference between OUT and REFOUT, divided by the selected gain
of either 50 or 100, when V
SENSE
= V
RS+
- V
RS-
= 0V.
Note 6:
The negative full-scale sense voltage is limited by the voltage range of OUT from V
REFOUT
to GND.
Note 7:
Total OUT Voltage Error is the sum of offset voltage and gain errors. The output voltage is measured relative to the reference
