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
