General Description

The AH342 is a bipolar latching hall IC with a pair of

complementary push/pull outputs. A dual hall

element is used to offset stress induced noise and

drift. The robust outputs are capable of sourcing up

to 7.4mA and sinking up to 4.4mA. The device

contains inherent reverse polarity protection up to

the full power supply range.
