AD5220B10

The AD5220B10 is one member of the AD5220 family which designed as the single channel, 128-position digitally controlled variable resistor (VR) device. It can be used in (1)mechanical potentiometer replacement; (2)remote incremental adjustment applications; (3)instrumentation: gain, offset adjustment; (4)programmable voltage-to-current conversion; (5)programmable filters, delays, time constants; (6)line impedance matching; (7)power supply adjustment. And contains a fixed resistor with a wiper contact that taps the fixed resistor value at a point determined by a digitally controlled UP/DOWN counter. Featur-es of the AD5220B10 are:(1)increment/decrement count control;(2)very low power: 40 mA max;(3)10 kV, 50 kV, 100 kV;(4)potentiometer replacement;(5)128 position.

The absolute maximum ratings of the AD5220B10 can be summarized as:(1)VDD to GND:-0.3 to +7 V;(2)VA, VB, VW to GND:0 V, VDD;(3)AXBX, AXWX, BXWX:±20 mA;(4)digital input voltage to GND:0 V to VDD+0.3 V;(5)operating temperature range:-40°C to +85°C;(6)maximum junction temperature:+150°C;(7)storage temperature:-65°C to +150°C;(8)lead temperature (soldering, 10 sec):+300°C.
