FUNCTION
Resistor B High Terminal. The voltage at HB can be higher or lower than the voltage at LB.
Current can flow into or out of HB.
Resistor B Wiper Terminal
Resistor B Low Terminal. The voltage at LB can be higher or lower than the voltage at HB.
Current can flow into or out of LB.
Internally Connected. Connect to GND.
Ground
No Connection. Not internally connected.
Internal Power-Supply Bypass. For additional charge-pump filtering, bypass to GND with a
capacitor close to the device.
Active-Low Chip-Select Input
Serial-Interface Data Input
Serial-Interface Clock Input
Power-Supply Input. Bypass VDD to GND with a 0.1µF capacitor close to the device.
Resistor A High Terminal. The voltage at HA can be higher or lower than the voltage at LA.
Current can flow into or out of HA.
Resistor A Wiper Terminal
Resistor A Low Terminal. The voltage at LA can be higher or lower than the voltage at HA.
Current can flow into or out of LA.
Exposed Pad (MAX5391 Only). Connect to GND.
