DS1854 Datasheet

DS1854 Dual Temperature-Controlled Resistors

The DS1854 dual temperature-controlled nonvolatile (NV) variable resistors with two monitors consists of two 50kΩ 256-position linear variable resistors, two analog monitor inputs (MON1, MON2), and a direct-to-digital temperature sensor. The device provides an ideal method for setting and temperatur.
