Note 1:
All devices are 100% production tested at T
A
= +25
°
C. All temperature limits are guaranteed by design.
Note 2:
V
REF
is defined as the average voltage of V
REF1A
and V
REF1B
. REF1B is usually connected to REF1A or GND.
V
SENSE
is defined as V
RS+
- V
RS-
.
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 V
SENSE
and the device
’
s gain, either RS+ or RS- can extend below 4.5V by the device
’
s typical full-scale value of
V
SENSE
.
Note 4:
Negative V
SENSE
applies to MAX4081 only.
Note 5:
V
SENSE
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:
V
OS
is extrapolated from the gain accuracy test for the MAX4080 and measured as (V
OUT
- V
REF
)/A
V
at V
SENSE
= 0V, for the
MAX4081.
Note 7:
V
SENSE
is:
MAX4080F, 500mV
MAX4080T, 125mV
MAX4080S, 50mV
MAX4081F/T/S, 0V

REF1A
= 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.
