INA190-Q1-–-40V-BI-DIRECTIONAL-ULTRA-PRECISE-CURRENT-SENSE-AMPLIFIER

INA190-Q1 – 40V, BI-DIRECTIONAL, ULTRA-PRECISE CURRENT SENSE AMPLIFIER

The INA190-Q1 is an automotive, low-power, voltage-output, current-shunt monitor (also called a current-sense amplifier). This device is commonly used for monitoring systems directly connected to an automotive 12-V battery. The INA190-Q1 can sense drops across shunts at common-mode voltages from –0.2 V to +40 V, independent of the supply voltage. In addition, the input pins have an …
