Functional Block Diagram
A1356
Description
The A1356 device is a high precision, programmable open
drain Hall-effect linear sensor IC with a pulse width modulated
(PWM) output. The duty cycle (D) of the PWM output signal
is proportional to an applied magnetic field. The A1356 device
converts an analog signal from its internal Hall element 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 the A1356 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 for a greater sampling
rate, which increases the accuracy of the output signal and
results in faster signal processing capability.
The A1356 sensor is provided in a lead (Pb) free 3-pin single
inline package (KB suffix), with 100% matte tin leadframe
plating.
