General Description
The MX8682 is a 12 Bit Digital Output Magnetic Flux Sensor.
The device is a complete sampled data subsystem that converts
a magnetic flux intensity of ±100 Gauss full scale into a 12-bit
digital output word. 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 adjustable exponentially weighted moving average digital
filter is included that is capable of improving the signal to noise
ratio while reducing the signal bandwidth. 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 MX8682 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.
