 Description
The DIO2488 is a voltage output, high-side and
low-side current-shunt monitor. The device sense
drops across shunts at common-mode voltages from
-0.1 V to 30 V, independent of the single supply
voltage. Three fixed gains are available: 20 V/V, 50
V/V, 100 V/V, 200 V/V. The DIO2488 is designed to
use for overcurrent detection, voltage feedback
control loops, or as a power monitor. The low offset of
the zero-drift architecture enables lower full-scale
drops across the shunt and high-precision
measurements with very low input offset voltage.
The device operates from a single 2.7 V to 30 V
power supply or a dual ±1.35 V to ±15 V with low
quiescent current. The device is specified over
ambient temperature range from -40°C to 125°C,
which makes it a perfect solution for industrial and
consumer applications.
