DS1854 Datasheet Dual Temperature-controlled Resistors

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: Rev 0; 1/03 Dual Temperature-Controlled Resistors with Two Monitors General.

General Description

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 temperature-compensating bias voltages and currents in control applications using minimal circuitry.

The variable resistor settings are stored in www.DataSheet4U.com EEPROM memory and can be accessed over the 2-wire serial bus.

Key Features

  • Four Total Monitored Channels (Temperature, VCC, MON1, MON2).
  • Two External Analog Inputs (MON1, MON2).
  • Internal Direct-to-Digital Temperature Sensor.
  • Two 50kΩ, Linear, 256-Position, Nonvolatile Temperature-Controlled Variable Resistors.
  • Resistor Settings Changeable Every 2°C.
  • Access to Monitoring and ID Information Configurable with Separate Device Addresses.
  • Resistor Disable (Open-Circuit) Function.
  • 2-Wire Serial Interface.
