PRECISION HIGH VOLTAGE HIGH-SIDE CURRENT MONITORS 
 
Description 
The ZXCT1082 and ZXCT1083 are high side unipolar
current sense monitors. These devices eliminate the need to
disrupt the ground plane when sensing a load current.
The ZXCT1082/1084/1086 have 60V maximum operating
voltage   and   ZXCT1083/1085/1087   have   40V   maximum
operating voltage.
The   wide   common-mode   input   voltage   range   and   low
quiescent currents coupled with SOT25 packages make
them   suitable   for   a   range   of   applications;   including
automotive and systems operating from industrial 24-28V
rails.
Their quiescent current is only 0.6礎 thereby minimizing
current sensing error.
The   ZXCT1082   and   ZXCT1083   use   three   external
transconductance/gain   setting   resistors   which   increase
versatility by permitting wide gain ranges and optimization of
bandwidths.
The   ZXCT1084/5/6/7   are   fixed   gain   voltage   output
counterparts of the ZXCT1082/3.
