Type Description
Analog in Programs output voltage. Only active when A-ENAB is low.
Analog in Programs output current. Only active when A-ENAB is low.
Reference voltage. Can be connected to VPROG or IPROG directly to
Analog out program full scale, or through potentiometers to adjust programmed
values.
Ground Ground for digital inputs and outputs.
Digital in Analog Enable. Enables analog programming when low.
Digital out Over-temperature status indicator. High when OT is tripped.
Analog out Voltage monitor signal.
