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.
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.

This variant is in production, however, it has been deemed Pre-End of Life. The product is approaching end of life. Within a minimum of 6 months,
the device will enter its final, Last Time Buy, order phase. Status change: January 31, 2011. Suggested replacements: for the A1321ELHLT-T and
the A1321LLHLT-T use the A1324LLHLX-T, for the A1322LLHLT-T use the A1325LLHLX-T, and for the A1323LLHLT-T use the A1326LLHLX-T.

Variant is in production but has been determined to be NOT FOR NEW DESIGN. This classification indicates that sale of the variant is currently
restricted to existing customer applications. The variant should not be purchased for new design applications because obsolescence in the near
future is probable. Samples are no longer available. Status change: January 31, 2011.
