A1321, A1322,
and
A1323
Ratiometric Linear Hall Effect Sensor
for High-Temperature Operation
The A132X family is provided in a 3-pin single in-line package
(UA) and a 3-pin surface mount package (LH). Each package is
available in a lead (Pb) free version (suffix, –T) , with a 100% matte
tin plated leadframe.
Description (continued)
recoverability after temperature cycling. Having the Hall element
and an amplifier on a single chip minimizes many problems normally
associated with low-level analog signals.
Output precision is obtained by internal gain and offset trim adjustments
made at end-of-line during the manufacturing process.

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 obsolescence 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: A1322ELHLT, A1322EUA, and A1323LLHLT.
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: A1321ELHLT, A1321EUA, A1321LLHLT, A1321LUA,
