Note 1:
All devices are 100% production tested at T
A
= +25°C. All temperature limits are guaranteed by product
characterization.
Note 2:
Extrapolated to V
OUT
= 0. I
CC
is the total current into the RS+ and the RS- pins.
Note 3:
Input offset voltage V
OS
is extrapolated from V
OUT
with V
SENSE
set to 1mV.
Note 4:
Gain error is calculated by applying two values for V
SENSE
and then calculating the error of the actual slope vs. the
ideal transfer characteristic:
For GAIN = 25, the applied V
SENSE
is 20mV and 120mV.
For GAIN = 50, the applied V
SENSE
is 10mV and 60mV.
For GAIN = 100, the applied V
SENSE
is 5mV and 30mV.
For GAIN = 200, the applied V
SENSE
is 2.5mV and 15mV.
Note 5:
The device is stable for any capacitive load at V
OUT
.
Note 6:
V
OH
is the voltage from V
RS-
to V
OUT
with V
SENSE
= 3.6V/GAIN.
