APS11205LLHALT

P1-P3P4-P6P7-P9P10-P12P13-P13
DESCRIPTION
The APS11205 Hall-effect sensor IC is an extremely
temperature-stable and stress-resistant device, especially suited
for operation over extended junction temperature ranges up
to 175°C. Superior high-temperature performance is made
possible through dynamic offset cancellation, which reduces the
residual offset voltage normally caused by device overmolding,
temperature dependencies, and thermal stress.
The single silicon chip includes: a Hall plate, small signal
amplifier, chopper stabilization, Schmitt trigger, and a short-
circuit-protected open-drain output. A south pole of sufficient
strength turns the output on. Removal of the magnetic field
turns the output off. For applications requiring operation from
greater than 5.5 V, or operation directly from a battery, refer
to the A1120.
Two package styles provide a choice of through-hole or surface
mounting. Package type LH is a modified SOT23W, surface-
mount package, while UA is a three-lead ultra-mini SIP for
through-hole mounting. Both packages are lead (Pb) free and
RoHs compliant with 100% matte-tin leadframe plating.
