Description
The A1301 and A1302 are continuous-time, ratiometric, linear
Hall-effect sensor ICs. They are optimized to accurately provide
a voltage output that is proportional to an applied magnetic
field. These devices have a quiescent output voltage that is
50% of the supply voltage. Two output sensitivity options
are provided: 2.5 mV/G typical for the A1301, and 1.3 mV/G
typical for the A1302.
The Hall-effect integrated circuit included in each device
includes a Hall circuit, a linear amplifier, and a CMOS Class A
output structure. Integrating the Hall circuit and the amplifier
on a single chip minimizes many of the problems normally
associated with low voltage level analog signals.
High precision in output levels is obtained by internal gain
and offset trim adjustments made at end-of-line during the
manufacturing process.
These features make the A1301 and A1302 ideal for use in
position sensing systems, for both linear target motion and
rotational target motion. They are well-suited for industrial
applications over extended temperature ranges, from –40°C
to 125°C.
Two device package types are available: LH, a 3-pin SOT23W
type for surface mount, and UA, a 3-pin ultramini SIP for
through-hole mount. They are lead (Pb) free (suffix, –T) with
100% matte tin plated leadframes.
