Descriptions
The DIO2388X series of voltage output current
shunt monitors can sense drops across shunts at
common-mode voltages from -0.3 V to 26 V,
independent of the supply voltage. Two fixed gains
are available: 50 V/V and 100 V/V. The low offset of
the Zero-Drift architecture enables current sensing
with maximum drops across the shunt as low as 10
mV full-scale.
These devices operate from a single 2.7 V to 26 V
power supply, drawing a maximum of 100 μA of
supply current. All versions are specified from
-40°C to 105°C, and offered in both SC70-6 and
QFN1.4*1.8-10 packages.
