com ZXCT1020 ZXCT1020 Low offset current output current monitor Description The ZXCT1020 is a precision high-side current sense monitor.
Using this type of device eliminates the need to disrupt the ground plane when sensing a load current.
The ZXCT1020 uses two external resistors to set the overall voltage gain for applications where improved accuracy at small sense voltages is required.
For fixed gain variants Zetex offers the ZXCT1021 (G=10) and ZXCT1022 (G=100).
The ZXCT1020 footprint follows that of the ZXCT1021/2 with only 2 additional resistors required: One resistor between pins 1 and 4 for setting transconductance, and the other between pins 3 and 2 for setting overall gain.
Current output enables the user to set the gain via these external resistors.
Using two external resistors to set the gain ensures optimal versatility as the transconductance can be varied to meet the output impedance requirements of the load that the ZXCT1020 has to drive.
The very low off...
