Description

Magnet Field Magnitude RaNGe warning; active low, indicates that the magnetic field

strength is outside of the recommended limits.

Mode input. Select between low noise (low, connect to VSS) and high speed (high,

connect to VDD5V) mode at power up. Internal pull-down resistor.

Chip Select, active low; Schmitt-Trigger input, internal pull-up resistor (~50kΩ)

Clock Input of Synchronous Serial Interface; Schmitt-Trigger input

must be left unconnected

Data Output of Synchronous Serial Interface

Negative Supply Voltage (GND)

OTP Programming Input and Data Input for Daisy Chain mode. Internal pull-down resistor

(~74kΩ).

Should be connected to VSS if programming is not used

DAC Reference voltage input for external reference
