Note 5:
Gain error applies to current flow in either direction and 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 6:
The device is stable for any capacitive load at V
OUT
.
Note 7:
V
OH
is the voltage from V
RS-
to V
OUT
with V
SENSE
= 3.6V/GAIN.
