Product Overview
NSI1300-Q1 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 ±50mV (±64mV full-scale)
or ±250mV (±320mV full-scale). The differential input is
ideally suited to shunt resistor-based current sensing in
high voltage applications where isolation is required.
The device has a fixed gain (8.2 or 41) 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.
