DS1856E-050+
Digital Potentiometer ICs Dual, Temperature-Controlled Resistors with Internally Calibrated Monitors and Password Protection
Brands: Analog Devices Inc./Maxim Integrated
Mfr.Part #: DS1856E-050+
Datasheet: DS1856E-050+ Datasheet (PDF)
Package/Case: 16-TSSOP(0.173",4.40mmWidth)
DS1856E-050+ 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-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 EEPROM memory and can be accessed over the 2-wire serial bus.
