OVERVIEW

The DS1846 NV tri-potentiometer, memory, and MicroMonitor™ consists of two 10kꢁꢂꢃ100-position

linear taper potentiometers, one 100kꢁꢂꢃ256-position linear taper potentiometer; 256 bytes of EEPROM

memory; and a MicroMonitor. The device provides an ideal method for setting bias voltages and currents

in control applications using a minimum of circuitry.
