The DS3906U+ is a triple, non-volatile, low step size variable resistor plus memory in 10 pin μSOP package. It is a variable digital resistor capable of ohm and subohm increments when used in parallel with a fixed external resistor. All three of the DS3906's resistors have 64 positions (plus a high Z state) with a pseudo-log response cleverly chosen to have a linear equivalent resistance when paired with an external resistor. The device contains 16 bytes of user EEPROM which is controlled through an I2C compatible serial interface.
Supply voltage range is 2.7V to 5.5V
Operating temperature range from -40°C to 85°C
Three address pins allow up to eight DS3906s on the same I2C bus
Resistor settings are stored in non-volatile memory
