ELECTRICAL CHARACTERISTICS (continued)
(V

RS-
= 3.6V, V
SENSE
= (V
RS+
- V
RS-
) = 0, T
A
= -40°C to +85°C, unless otherwise noted. Typical values are at T
A
= +25°C.)
(Note 1)
Note 1: All devices are 100% production tested at T
A
= +25°C. All temperature limits are guaranteed by design.
Note 2: V
OUT
= 0V. I
CC
is the total current into RS+ plus RS-.
Note 3: V
OS
is extrapolated from measurements for the Gain Error test.
Note 4: Gain Error is calculated by applying two values of V
SENSE
and calculating the error of the slope, vs. the ideal:
G = 25: V
SENSE
20mV and 120mV
G = 50: V
SENSE
10mV and 60mV
G = 100: V
SENSE
5mV and 30mV
Note 5: The device is stable for any external capacitance value.
Note 6: V
OH
is the voltage from V
RS-
to V
OUT
with V
SENSE
= 3.6V/Gain.
