MAXIM INTEGRATED / ANALOG DEVICES DS1859E050 Dual Temperature Resistor
The DS1859E-050+ is a dual, temperature-controlled resistor with an internally calibrated monitor, housed in a 16-pin TSSOP package. It features two 50 kΩ, 256-position linear variable resistors, three analog monitor inputs (MON1, MON2, MON3), and a built-in digital temperature sensor. The device is designed for setting and temperature compensating bias voltages and currents in control systems, requiring minimal circuitry. Resistor settings are stored in EEPROM and accessible via a 2-wire serial interface. It operates across a supply voltage range of 2.85V to 5.5V and an ambient temperature from -40°C to 95°C. The device supports five monitored channels, including temperature, VCC, and the three monitor inputs, with alarms and warnings for each. Settings can be adjusted every 2°C, and monitoring information is accessible with configurable device addresses. Additional features include internal buffers with TTL/CMOS compatible inputs and open-drain outputs. Typical applications include optical transceivers, optical transponders, instrumentation, industrial controls, RF power amplifiers, and diagnostic monitoring.
