DESCRIPTION
The DS1855 dual nonvolatile (NV) digital potentiometer and secure memory consists of one100-position linear taper potentiometer, one256-position linear taper potentiometer, 256 bytes of EEPROM memory, and a 2-wire interface. The DS1855, which features a new software write protect, is an upgrade of the DS1845. The DS1855 provides an ideal method for setting bias voltages and currents in control applications using a minimum of circuitry.
