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.

♦ Three 256-Position Linear Digital Resistors
