Description
1,2
Bi-directional I/O. Can also be used as input to A/D converter. I/O can be
controlled by serial communications or by firmware as alarm inputs or level
out. (unconnected when not used)
Test pin for Melexis production testing. (in normal application connected to
VDD)
Filter pin; allows for connection of a capacitor to the internal analog path.

OFC
Offset control output. Provides access to the internal programmed offset
control voltage for use with external circuitry. (unconnected when not used)
Bridge inputs, negative and positive.

TMP
Temperature sensor input. An external temperature sensor can be used in
conjunction with the internal one. The external sensor can provide a
temperature reading at the location of the bridge sensor.
Regulated supply voltage. Used for internal analog circuitry to ensure accurate
and stable signal manipulation.
Regulator FET gate control. For generating a stable supply for the bridge
sensor and internal analog circuitry (generates regulated voltage for VDD).
Unregulated supply voltage. Used for digital circuitry and to generate FET
output.
Voltage mode output. Compensated sensor output voltage.
