General Description
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 configura-
tion. The selected register determines the value of the
variable resistor. Additionally, all three resistors have a
high-impedance setting. Resistor R0 has the additional
flexibility of allowing an external shunt resistor to pro-
vide increased dynamic range. Internal address set-
tings allow the DS3901 slave address to be
programmed to one of 128 possible addresses. The
DS3901 also features an optional password-protection
scheme that allows the protection of sensitive data.
