The INA190-EP is a low-power, voltage-output,
current-shunt monitor (also called a current-sense amplifier). This device is commonly used
for overcurrent protection, precision current measurement for system
optimization, or in closed-loop 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.
