DS1856 - Temperature-Controlled Resistors

General Description

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.

Key Features

  • password protection equivalent to the DS1852, further enhancing compatibility between the two. Features.
  • SFF-8472 Compatible.
  • Five Monitored Channels (Temperature, VCC, MON1, MON2, MON3).
  • Three External Analog Inputs (MON1, MON2, MON3) That Support Internal and External Calibration.
  • Scalable Dynamic Range for External Analog Inputs.
  • Internal Direct-to-Digital Temperature Sensor.
  • Alarm and Warning Flags for All Monitored Channels.
  • Tw.

www.DataSheet4U.com Rev 1; 4/05 Dual, Temperature-Controlled Resistors with Internally Calibrated Monitors and Password Protection General Description 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 applications using minimal circuitry. The variable resistor settings are stored in EEPROM memory and can be accessed over the 2-wire serial bus. Relative to other members of the family, the DS1856 is essentially a DS1859 with a DS1852-friendly memory map.
