• Manufacturer Part Number: A1391SEHLT-T
• Manufacturer: Allegro

A1391, A1392,
A1393, and A1395
Description (continued)
Despite the low power consumption of the circuitry in the A139x,
the features required to produce a highly-accurate linear Hall effect
IC have not been compromised. Each BiCMOS monolithic circuit
integrates a Hall element, improved temperature-compensating
circuitry to reduce the intrinsic sensitivity drift of the Hall element,
a small-signal high-gain amplifier, and proprietary dynamic

offset cancellation circuits. End of line, post-packaging, factory
programming allows precise control of device sensitivity and
offset.
These devices are available in a small 2.0 × 3.0 mm, 0.75 mm nominal
height microleaded package (MLP/DFN). It is Pb (lead) free, with
100% matte tin leadframe plating.
