Product Description

onsemi NCS211RMUTAG Rail to Rail Current Sensing Amplifier is a single-channel device packaged in a compact 10-Pin UQFN. Designed for industrial, automotive, and power electronics applications, it provides accurate current sensing across a wide common mode voltage range from -0.3 V to 26 V independent of supply voltage. With its fixed gain of 500 V/V and a zero-drift architecture, it achieves low offset voltage of ±150 μV and very low offset drift of 0.5 μV/°C, making it highly reliable for precise measurement.

The amplifier operates on a single supply voltage ranging from 2.2 V to 26 V and features a low supply current of 60 μA, making it suitable for power-efficient systems. Its rail-to-rail output ensures maximum dynamic range and compatibility with modern low voltage data acquisition systems. The device is automotive grade, certified to AEC-Q101, and supports high side current sensing in high voltage systems, with gain bandwidth product of 25 kHz, enabling responsive signal conditioning.

This amplifier is ideal for applications including power adapters, LED power supplies, automotive lighting controls, laptop/notebook power management, fast charging circuits for smartphones and tablets, telecom DC-DC modules, and various closed loop feedback systems. It provides accurate measurement with high CMRR of 105 dB to maintain signal fidelity in noisy environments.

The device measures just 1.4 mm in length and 0.55 mm in height, enabling space-saving PCB designs. Its surface mount UQFN package is well-suited for modern compact electronics manufacturing. The product contains a single amplifier channel with 10 pins, facilitating straightforward integration into existing circuits.

Operates from 2.2 V to 26 V single supply voltage. Fixed gain of 500 V/V for current sensing. Low offset voltage and offset drift for accuracy. Low supply current of 60 μA for power efficiency. Wide operating temperature range: -40°C to 125°C.

Compact surface mount 10-pin UQFN package. High side current sensing for high voltage systems. Automotive standard AEC-Q101 compliant. CMRR of 105 dB for noise rejection. Length and height of 1.4 mm and 0.55 mm respectively.
