Application Note
(Continued)
This represents a value that the LMP8271 and LMP8276
have not been optimized and trimmed for and may very well
be above the limits indicated in the electrical characteristics
tables.
Midrail Offset Adjustment Pin
The external midrail offset adjustment pin enables the user
to utilize this device for bidirectional current sensing. If the
offset pin, pin 7, is connected to ground then the LMP8271,
LMP8276 are capable of sensing positive signals. When the
offset pin is connected to V
then 1/2V
is added to the
output and under this condition the amplifier can sense both
positive and negative signals. If this offset pin is connected
to any voltage between ground and V
, then the output is
increased by a voltage equal to half of that offset, e.g. If the
offset is connected to V
X
, then the output increases by
1/2V
X
. The following figure shows how this works:
Note that the offset pin, pin 7, needs to be connected at all
times. If the pin is left floating, the LMP8271 and LMP8276
will be operating in an undefined mode. Also pin 7 should be
driven from a low impedance source.
