76V, High-Side, Current-Sense Amplifiers with

Voltage Output

DC ELECTRICAL CHARACTERISTICS (continued)

(VCC = VRS+ = 4.5V to 76V, VREF1A = VREF1B = 5V (MAX4081 only), VSENSE = (VRS+ - VRS-) = 0, RLOAD = 100kΩ, TA = TMIN to TMAX,

unless otherwise noted. Typical values are at TA = +25°C.) (Notes 1, 2)
