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 word, (10-bit resolution). The sensor
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.
