1 Features 3 Description •
•
•
• The INA190 series of devices are voltage-output,
current-shunt monitors (also called current-sense
amplifiers). These devices are commonly used for
overcurrent
protection,
precision
current
measurement for system optimization, or in closedloop feedback circuits. This series of devices can
sense drops across shunts at common-mode
voltages from –0.2 V to +40 V, independent of the
supply voltage. Five fixed gains are available: 25 V/V,
50 V/V, 100 V/V, 200 V/V, or 500 V/V. The low input …
