MICROPOWER FIXED GAIN OF 50 CURRENT MONITOR
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.
