ELECTRICAL CHARACTERISTICS (continued)
(VCC = 5V, VRS+ = VRS- = +14V, VSENSE = (VRS+ - VRS-) = 0V, VSHDN = VGND = 0V, VREFIN = VCC/2, RL = 100kΩ; for MAX9918, AV =
90V/V, R2/R1 = 89k
Ω/1kΩ; for MAX9920, AV = 20V/V, R2/R1 = 79kΩ/1kΩ; TA = -40°C to +125°C, unless otherwise noted. Typical val-
ues are at TA = +25°C.) (Note 1)

Note 1: All devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by design.
Note 2: VOS is extrapolated from two point gain error tests. Measurements are made at VSENSE = 5mV and 50mV for
MAX9918/MAX9919N/MAX9919F, and VSENSE = 20mV and 200mV for MAX9920.
Note 3: Extrapolated VOS as described above in Note 2 is used to calculate VOS drift, CMRR, and PSRR.
Note 4: OUT should be 100mV away from either rail to achieve rated accuracy, or limited by a VSENSE of 50mV for the
MAX9918/MAX9919N/MAX9919F and 200mV for the MAX9920.
Note 5: Not production tested. Guaranteed by design.
