DS1856 - Maxim Integrated Products

DS1856 Temperature-Controlled Resistors

The DS1856 dual, temperature-controlled, nonvolatile (NV) variable resistors with three monitors consists of two 256-position, linear, variable resistors; three analog monitor inputs (MON1, MON2, MON3); and a direct-todigital temperature sensor. The device provides an ideal method for setting and temperature-compensating bias voltages and currents in control.

Features

password protection equivalent to the DS1852, further enhancing compatibility between the two.
