Description
The A 3211 and A3212 integrated circuits are ultra-sensitive,
pole in de pen dent Hall-effect switches with latched digital
output. These sensors are es pe cial ly suited for operation in
battery-operated, hand-held equip ment such as cellular and
cordless tele phones, pagers, and palmtop com put ers. A 2.5
volt to 3.5 volt operation and a unique clocking scheme reduce
the average op er at ing power requirements to less than 15 μW
with a 2.75 volt supply.
Unlike other Hall-effect switches, either a north or south pole
of suf fi cient strength will turn the output on in the A3212,
and in the absence of a magnetic field, the output is off. The
A3211 provides an inverted output. The polarity independence
and minimal power requirements allow these devices to easily
replace reed switches for superior reliability and ease of
manufacturing, while eliminating the requirement for signal
conditioning.
Improved stability is made possible through chopper
stabilization (dynamic offset cancellation), which reduces the
residual offset voltage normally caused by device overmolding,
temperature de pen den cies, and thermal stress.
