The A3507– and A3508– are sensitive, temperature-stable linear
Hall-effect sensors. Ratiometric, linear Hall-effect sensors provide a
voltage output that is proportional to the applied magnetic field and have
a quiescent output voltage that is approximately 50% of the supply
voltage. These magnetic sensors are ideal for use in linear and rotary
position sensing systems in the harsh environments of automotive and
industrial applications over extended temperatures to -40°C and +150°C.
The two devices are similar except for temperature stability over the
operating temperature range. See the Magnetic Characteristics table for
complete, individual device parametrics.
Each monolithic circuit integrates a quadratic Hall element, im-
proved temperature compensating circuitry to reduce the intrinsic
sensitivity drift of the Hall element, a small-signal high-gain amplifier,
and a rail-to-rail low-impedance output stage. Many problems normally
associated with low-level analog signals are minimized by having the
Hall element and amplifier in a single chip. Output precision is obtained
by internal gain and offset trim adjustments during the manufacturing
process.
The first character of the part number suffix determines the device
operating temperature range: suffix ‘S–’ is for -20°C to +85°C, suffix
‘E–’ is for -40°C to +85°C, and suffix ‘L–’ is for -40°C to +150°C.
These devices are supplied in a 3-pin ultra-mini-SIP ‘–UA’ package.

Negative current is defined as coming out of (sourcing) the output.
* This test requires positive and negative fields sufficient to swing the output driver between fully OFF and saturated (ON), respec-
tively. It is NOT intended to indicate a range of linear operation.

Magnetic flux density is measured at most sensitive area of device located 0.018" (0.46 mm) below the branded face of the “UA”
package.
* See Characteristics Definitions for test conditions.
† The nominal sensitivity temperature stability is designed to compensate for the temperature coefficient of samarium-cobalt
magnets (-0.02%/°C).
‡ This calculation (formula 1, next page) yields the device’s equivalent accuracy, over the operating temperature range, in gauss.
