SiSA4080 is a 76V capable current sense amplifier produced

using SOI (Silicon-On-Insulator) technology. A wide power

supply range of 4.5V - 76V applies to both input common-

mode and supply voltages for simplified high-voltage current

monitoring. The device can be powered by the same voltage

being monitored and requires no intermediate supply voltage

routed to the point of load. High-side current monitoring avoids

ground path interference with the measured load and is

functionally suited for high-voltage precision applications.

SiSA4080 is a fixed 60V/V gain device and is specified for

operation over a wide -40°C to +125° temperature range. A

user selectable external sense resistor sets the full-scale

current reading and its proportional output voltage.

Optimized design + fab process deliver an industry smallest

die with exceptional stability. This device suits applications

requiring very high integration and reliability over temperature.
