OVERVIEW
The DS1846 NV tri-potentiometer, memory, and MicroMonitor consists of two 10k
linear taper potentiometers, one 100k
256-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.
