ZXCT1020

Low offset current output current monitor

Description

The ZXCT1020 is a precision high-side current Current output enables the user to set the gain

sense monitor. Using this type of device via these external resistors. Using two external

eliminates the need to disrupt the ground resistors to set the gain ensures optimal

plane when sensing a load current.

versatility as the transconductance can be varied

to meet the output impedance requirements of

the load that the ZXCT1020 has to drive.

The ZXCT1020 uses two external resistors to

set the overall voltage gain for applications

where improved accuracy at small sense The very low offset voltage enables a typical
