ONNCS21674DMG050R2G
Overview
The NCS21674DMG050R2G is a dual-channel, high-side or low-side current sense amplifier featuring a fixed gain of 50 V/V. It is designed to measure small differential voltages across a sense resistor while operating with a wide common-mode input range of -0.1V to 40V. This AEC-Q100 qualified component is optimized for precision power monitoring in space-constrained automotive and industrial environments.
Why Choose This Part
This device offers a low input offset voltage of 100 uV and a 350 kHz bandwidth, providing a high degree of accuracy for dynamic current measurements. Its dual-channel configuration in a compact Micro8 package allows for high-density PCB layouts, while the 195 uA per channel supply current minimizes power overhead in battery-operated systems.
Applications
Key Specifications
Getting Started
When designing with this part, place a 0.1uF ceramic bypass capacitor close to the VDD pin and ensure the shunt resistor is Kelvin-connected to the IN+ and IN- pins to minimize trace resistance errors. Since this is a fixed-gain amplifier (50 V/V), select your shunt resistor such that the maximum expected current produces a differential voltage that keeps the output within the 2.7V to 5.5V supply rail limits. Evaluation can be performed using generic MSOP-8 breakout boards if a dedicated development kit is unavailable.
