Product Summary
The NCS2167* series of current sense amplifiers can sense the voltage drop across a current sense resistor at common mode voltages from-0.1 V to 40 V, regardless of the supply voltage.
These devices can operate from a single 2.7V to 5.5V power supply.
NCS21673 is a single product, packaged in TSOP-5.
NCS21674 is a dual product and the package is Micro-8.
