Triple, 8-Bit NV Variable Resistor  
with Dual Settings and User EEPROM  
General Description  
Features  
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.
