3 Description
The INA190-EP is a low-power, voltage-output,
current-shunt monitor (also called a currentsense
amplifier). This device is commonly
used for overcurrent protection, precision current
measurement for system optimization, or in closedloop
feedback circuits. The INA190-EP can sense
drops across shunts at common-mode voltages from
–0.2 V to +40 V, independent of the supply voltage.
The low input bias current of the device permits the
use of larger current-sense resistors, thus providing
accurate current measurements in the microamp
range. The low offset voltage of the zero-drift
architecture extends the dynamic range of the current
measurement. This feature allows for smaller sense
resistors with lower power loss, while still providing
accurate current measurements.
The INA190-EP operates from a single 1.7-V to 5.5-
V power supply, and draws a maximum of 65 μA
of supply current when enabled; only 0.1 μA when
disabled. Five fixed gain options are available: 25 V/V,
50 V/V, 100 V/V, 200 V/V, or 500 V/V. The device
is specified over the operating temperature range of
–55°C to +150°C, and offered in the SOT-23 package.
