Description (continued)
This device includes on a single silicon chip a Hall-voltage gen-
erator, small-signal amplifier, chopper sta bi li za tion, a latch, and
a MOSFET output. Advanced CMOS processing is used to take
advantage of low-voltage and low-power requirements, compo-
nent matching, very low input-offset errors, and small component
geometries.

Package
Four package styles provide magnetically op ti mized solutions for
most ap pli ca tions. Miniature low-profile surface-mount package
types EH and EL (0.75 and 0.50 mm nominal height) are leadless,
LH is a 3-pin low-profile SMD, and UA is a three-pin SIP for
through-hole mount ing. Packages are lead (Pb) free (suffix, –T)
with 100% matte tin plated leadframes.
