Description
New applications for linear output Hall effect sensing, such
as current measurement, require both high accuracy and
increased sensor bandwidth. The Allegro
"
 A1360, A1361,
and A1362 programmable linear Hall effect sensor ICs are
designed specifically to achieve both goals. Available in a
through-hole SIP (single in-line package), the A136x Hall
effect sensor ICs are sensitive and temperature-stable. The
accuracy of these devices is enhanced via programmability on
the device VOUT pin. A capacitor to ground on the FILTER
pin on the A136x can be used to tune the device bandwidth in
a range less than 50 kHz.
These ratiometric Hall effect sensor ICs provide a voltage
output that is proportional to the applied magnetic field. The
quiescent output voltage is user-adjustable around either
50% (bidirectional configuration) or 10% (unidirectional
configuration) of the supply voltage, V
CC
. The device sensitivity
is adjustable within three guaranteed ranges: 0.7 to 1.4 mV/G
(A1360), 1.4 to 4.5 mV/G (A1361), and 4.5 to 16 mV/G
(A1362).
Each BiCMOS monolithic circuit integrates a Hall element,
temperature-compensation circuitry to reduce the intrinsic
sensitivity drift of the Hall element, a small-signal high-gain
amplifier, a clamped low-impedance output stage, and a
proprietary dynamic offset cancellation technique.
