Description
The A1354 device is a high precision, programmable 2-wire
Hall effect linear sensor IC with a pulse width modulated
(PWM) output. The duty cycle (D) of the PWM output signal
is proportional to the applied magnetic field. The A1354
device converts an analog signal from its internal Hall circuit
to a digitally encoded PWM output signal. The coupled noise
immunity of the digitally encoded PWM output is far superior
to the noise immunity of an analog output signal.
The BiCMOS, monolithic circuit inside of theA1354 integrates
a Hall element, precision temperature-compensating circuitry
to reduce the intrinsic sensitivity and offset drift of the Hall
element, a small-signal high-gain amplifier, proprietary
dynamic offset cancellation circuits, and PWM conversion
circuitry. The dynamic offset cancellation circuits reduce
the residual offset voltage of the Hall element. Hall element
offset is normally caused by device overmolding, temperature
dependencies, and thermal stress. The high frequency offset
cancellation (chopping) clock allows a greater sampling rate,
which increases the accuracy of the output signal and results
in faster signal processing capability.
The A1354 device is provided in a lead (Pb) free 4-pin single
inline package (KT suffix), with 100% matte tin leadframe
plating.
