General Description

The MX8683 is a 10-bit Digital Output Magnetic Flux
Sensor. The device is a complete sampled data
subsystem that converts a magnetic flux intensity of
±200 Gauss full scale into a 12-bit format digital
output
operates as a slave on the serial interface with TTL-
level compatible inputs SDI (serial data input), SCK
(serial clock), and CS* (chip select, active low).
Terminal SDO is the tri-state serial data output.
An optional exponentially weighted moving average
digital filter is included that averages the 10-bit ADC
output into a 12-bit output word. The digital filter has
a transfer function equivalent to a first order low
pass filter.
The full scale trim and/or the digital filter time
constant are controllable through the serial I/O
interface and are one-time programmable through
the serial interface (once programmed, the values
are loaded at every power-on).
The MX8683 can be mounted onto a PCB or
incorporated into a magnetic assembly and then
calibrated in-system through the serial interface.
The operating voltage range is 4.5V to 5.5V.

... At power-on the previous value is initialized to zero. A programmed change in A[2:0] does not reset the previous value. Therefore when using the filter, multiple samples must be taken at power-on or after changing A[2:0] before the filtered output will be correct.
