A1321, A1322, and A1323

Ratiometric Linear Hall Effect Sensor for High-Temperature Operation

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.

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.
