External References (MAX4081)
For the bidirectional MAX4081, the V
OUT
reference level
is controlled by REF1A and REF1B. V
REF
is defined as
the average voltage of V
REF1A
and V
REF1B
. Connect
REF1A and REF1B to a low-noise, regulated voltage
source to set the output reference level. In this mode,
V
OUT
equals V
REF1A
when V
SENSE
equals zero (see
Figure 4).
Alternatively, connect REF1B to ground, and REF1A to a
low-noise, regulated voltage source. In this case, the out-
put reference level (V
REF
) is equal to V
REF1A
divided by
two. V
OUT
equals V
REF1A
/2 when V
SENSE
equals zero.
In either mode, the output swings above the reference
voltage for positive current-sensing (V
RS+
> V
RS-
). The
output swings below the reference voltage for negative
current-sensing (V
RS+
< V
RS-
).
Applications Information
Recommended Component Values
Ideally, the maximum load current develops the full-
scale sense voltage across the current-sense resistor.
Choose the gain needed to yield the maximum output
voltage required for the application:
V
OUT
= V
SENSE
A
V
where V
SENSE
is the full-scale sense voltage, 1000mV
for gain of 5V/V, 250mV for gain of 20V/V, 100mV for
gain of 60V/V, and A
V
is the gain of the device.
In applications monitoring a high current, ensure that
R
SENSE
is able to dissipate its own I
2
R loss. If the resis-
tor
’
s power dissipation is exceeded, its value may drift
or it may fail altogether.
The MAX4080/MAX4081 sense a wide variety of cur-
rents with different sense-resistor values. Table 1 lists
common resistor values for typical operation.
