Application Information
The ZXCT1023 is line powered (derives its power from
the rail being sensed) this reduces the number of pins
used and PCB trace routing. The fixed gain of 50
reduces the PCB area by reducing the number of
external components. The only external component
required is the sense resistor. This coupled with the
1.2mm x 1.8mm TDFN package makes the solution size
very small.
The fixed gain of 50 has been chosen to meet the
normal requirements of most applications.
