AD5282BRUZ200-R7:  Single/Dual, +15 V/±5 V, 256-Position, I²C-Compatible Digital Potentiometer

The AD5280/AD5282 are single-channel and dual-channel, 256-position, digitally controlled variable resistors (VRs)*. The devices perform the same electronic adjustment function as a potentiometer, trimmer, or variable resistor. Each VR offers a completely programmable value of resistance between the A terminal and the wiper or the B terminal and the wiper. The fixed A-to-B terminal resistance of 20 kΩ, 50 kΩ, or 200 kΩ has a 1% channel-to-channel matching tolerance. The nominal temperature coefficient of both parts is 30 parts per million/ degrees centigrade (ppm/°C). Another key feature is that the parts can operate up to +15 V or ±5 V.

Wiper position programming defaults to midscale at system power-on. When powered, the VR wiper position is programmed by an I²C-compatible, 2-wire serial data interface. The AD5280/ AD5282 feature sleep mode programmability. This allows any level of preset in power-up and is an alternative to a costly EEPROM solution. Both parts have additional programmable logic outputs that enable users to drive digital loads, logic gates, LED drivers, and analog switches in their system.

The AD5280/AD5282 are available in thin, surface-mounted 14-lead TSSOP and 16-lead TSSOP. All parts are guaranteed to operate over the extended industrial temperature range of −40°C to +85°C. For 3-wire SPI-compatible interface applications, see the AD5260/AD5262 product information on www.BDTIC.com.
