ROHM Product Detail

BD14222G-C (New)
Automotive Current Sense Amplifier

The BD14222G-C is a current sense amplifier series. This device operates from a single 2.7V to 5.5V power supply. It has wide common mode voltage range from -14V to +40V, outputs analog voltage. The gain is 100 V/V. The matched gain resistor minimizes gain error and offset voltage. In additionally, the low input bias current is 1μA that reduces the offset on the path to shunt resistor.
