DS3901 Datasheet (Maxim Integrated Products)

DS3901, 8-Bit NV Variable Resistor

The DS3901 is a triple, 8-bit nonvolatile (NV) variable resistor.

Each of the resistors has two setting registers, which are selectable by software or by pin configuration.

The selected register determines the value of the variable resistor.

Additionally, all three resistors have a high-impedance se
