DS3901 Datasheet 8-bit Nv Variable Resistor

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: .. Rev 0; 4/06 Triple, 8-Bit NV Variable Resistor with Dual Settings and User.

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 configuration.

The selected register determines the value of the variable resistor.

Key Features

  • an optional password-protection scheme that allows the protection of sensitive data. Features o Three 256-Position Linear Digital Resistors o Full-Scale Resistances 50kΩ, 30kΩ, 20kΩ o Dual NV Settings for Each Resistor o o o o Low Temperature-Coefficient Resistors I2C.
  • Serial Interface Wide Operating Voltage (2.4V to 5.5V) Two-Level Password Write Protection DS3901 o 232 Bytes of User EEPROM o Programmable Slave Address o -40°C to +95°C Operating Temperature Range.
