External References (MAX4081)
For the bidirectional MAX4081, the VOUT reference level
is controlled by REF1A and REF1B. VREF is defined as
the average voltage of VREF1A and VREF1B. Connect
REF1A and REF1B to a low-noise, regulated voltage
source to set the output reference level. In this mode,
VOUT equals VREF1A when VSENSE 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 (VREF) is equal to VREF1A divided by
two. VOUT equals VREF1A/2 when VSENSE equals zero.
In either mode, the output swings above the reference
voltage for positive current-sensing (VRS+ > VRS-). The
output swings below the reference voltage for negative
current-sensing (VRS+ < VRS-).
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:
VOUT = VSENSE AV
where VSENSE 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 AV is the gain of the device.
In applications monitoring a high current, ensure that
RSENSE is able to dissipate its own I2R 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.
