Type
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
DAC output (unbuffered, Ri ~8kΩ)
Feedback, OPAMP inverting input
