High Reliability Reinforced

Isolated Amplifier

Datasheet (EN)1.0



Input common-mode overvoltage detection

Product Overview



Operation Temperature: -40℃~125℃

RoHS-Compliant Packages:

NSI1400 is a high-performance isolated amplifier with

output separated from input based on the NOVOSENSE

capacitive isolation technology. The device has a linear

differential input signal range of ±250mV (±320mV full-

scale). The differential input is ideally suited to shunt

resistor-based current sensing in high voltage

applications where isolation is required.

SOP8(300mil), SOP8(150mil)

Safety Regulatory Approvals



UL recognition:

The device has a fixed gain of 8.2 and provides a

differential analog output. The low offset and gain drift

ensure the accuracy over the entire temperature range.

High common-mode transient immunity ensures that

the device is able to provide accurate and reliable

measurements even in the presence of high-power

switching such as in motor control applications.

The fail-safe functions including input common-mode

overvoltage detection and missing VDD1 detection

simplify system-level design and diagnostics.
