76V, High-Side, Current-Sense Amplifiers with
Voltage Output
AC ELECTRICAL CHARACTERISTICS
(VCC = VRS+ = 4.5V to 76V, VREF1A = VREF1B = 5V (MAX4081 only), VSENSE = (VRS+ - VRS-) = 0V, RLOAD = 100k, CLOAD = 20pF,
TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Notes 1, 2)

Note 1: All devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by design.
Note 2: VREF is defined as the average voltage of VREF1A and VREF1B. REF1B is usually connected to REF1A or GND.
VSENSE is defined as VRS+ - VRS-.
Note 3: The common-mode range at the low end of 4.5V applies to the most positive potential at RS+ or RS-. Depending on the
polarity of VSENSE and the device’s gain, either RS+ or RS- can extend below 4.5V by the device’s typical full-scale value of
VSENSE.
Note 4: Negative VSENSE applies to MAX4081 only.
Note 5: VSENSE is:
MAX4080F, 10mV to 1000mV
MAX4080T, 10mV to 250mV
MAX4080S, 10mV to 100mV
MAX4081F, -500mV to +500mV
MAX4081T, -125mV to +125mV
MAX4081S, -50mV to +50mV
Note 6: VOS is extrapolated from the gain accuracy test for the MAX4080 and measured as (VOUT - VREF)/AV at VSENSE = 0V, for the
MAX4081.
Note 7: VSENSE is:
MAX4080F, 500mV
MAX4080T, 125mV
MAX4080S, 50mV
MAX4081F/T/S, 0V
VREF1B = VREF1A = 2.5V
Note 8: Output voltage is internally clamped not to exceed 18V.
Note 9: Output settles to within 1% of final value.
Note 10: The device will not experience phase reversal when overdriven.
