A1147 and
A1148
Low Current Ultrasensitive Two-Wire
Chopper-Stabilized Unipolar Hall Effect Switches
Description (continued)
feature on-chip transient protection and a Zener clamp to protect
against overvoltage conditions on the supply line.
The output currents of the A1148 switches HIGH in the presence
of a south (+) polarity magnetic field of sufficient strength, and
switches LOW otherwise, as in the presence of a weak field or a
north (–) polarity field. The A1147 has an opposite output: the
currents switch LOW in the presence of a south-polarity magnetic
field of sufficient strength, and switch HIGH otherwise.
Both versions are offered in two package styles. The LH is a SOT-
23W, miniature low-profile package for surface-mount applications.
The UA is a three-lead ultramini SIP for through-hole mounting.
Each package is available in a lead (Pb) free version (suffix, –T)
with 100% matte tin plated leadframe. Field-programmable versions
also available: A1180 and A1181.

1Pb-based variants are being phased out of the product line.
a. Certain variants cited in this footnote are in production but have been determined to be LAST TIME BUY. This classification indicates that sale of
this device is currently restricted to existing customer applications. The device should not be purchased for new design applications because obso-
lescence in the near future is probable. Samples are no longer available. Status change: October 31, 2006. Deadlilne for receipt of LAST TIME BUY
ORDERS: April 27, 2007. These variants include: A1147ELHLT, A1147EUA, A1147LLHLT, A1147LUA, A1148ELHLT, A1148EUA, and, A1148LLHLT.
b. Certain variants cited in this footnote are in production but have been determined to be NOT FOR NEW DESIGN. This classification indicates that
sale of this device is currently restricted to existing customer applications. The device should not be purchased for new design applications because
obsolescence in the near future is probable. Samples are no longer available. Status change: May 1, 2006. These variants include: A1148LUA.
