NCS7041D3G100R2G

Instrumentation, Op Amps, Buffer Amps Overview

The NCS7041D3G100R2G is a high-voltage, high-resolution current sense amplifier with a fixed gain of 100 V/V. It features a common-mode input voltage range from -6 V to 80 V and operates on a supply voltage between 3 V and 5.5 V. The device offers a gain bandwidth product of 100 kHz, a maximum gain error of ±0.3%, and a typical quiescent current of 1.5 mA. It supports bidirectional current measurements and includes accessible preamplifier and buffer pins for filtering or gain adjustment.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Supports unidirectional and bidirectional current sensing across a wide common-mode voltage range independent of the supply voltage
• Provides internal access to preamplifier output and buffer input for implementing low-pass filters or modifying gain
• Delivers precision performance with a maximum gain error of ±0.3% over the extended temperature range

Instrumentation, Op Amps, Buffer Amps Applications

• Telecom equipment power monitoring
• Power supply designs
• Diesel injection control systems
• Automotive solenoids and actuators

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the specific ordering suffix matches the required gain configuration and package type. Confirm whether the industrial NCS prefix or automotive NCV prefix is necessary based on application reliability standards. Ensure the selected variant aligns with the intended operating temperature range and PCB footprint requirements before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a fixed gain of 100 V/V is required for high-side or low-side current sensing applications. Consider the NCS7041 series if the design demands operation with common-mode voltages up to 80 V while maintaining a low single-supply voltage. Evaluate the need for external filtering capabilities provided by the A1 and A2 pins to optimize noise performance in noisy environments.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the NCS7041 family of current sense amplifiers manufactured by onsemi. The series provides multiple gain options including 14, 20, 50, and 100 V/V. The NCS7041 variant represents the industrial grade version, while the NCV7041 serves automotive applications requiring AEC-Q100 qualification and PPAP capability. Both share identical electrical characteristics and pinouts.
