Product Overview

NSI1312 is a cost-effective isolated amplifier with output

separated from input based on the NOVOSENSE capacitive

isolation technology Adaptive OOK®. The device has a

linear differential input signal range of ±1.2V (±1.5V full-

scale). The high input impedance of NSI1312 makes it

highly suitable for connection to high-voltage resistive

dividers or other voltage signal sources with high output

resistance.

SOW8 wide body (SOP8 300mil)

Safety Regulatory Approvals



UL recognition: 5000V_rmsfor 1 minute per UL1577

CQC certification per GB4943.1

CSA component notice 5A

The device has a fixed gain of 1 and provides differential

analog output version (NSI1312D-Q1) and single-ended

analog output version (NSI1312S-Q1) option.

DIN EN IEC 60747-17 (VDE 0884-17)

Applications

The low offset and gain drift ensure the accuracy over the

entire temperature range. The 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.
