- AD5280: 1 channel
- AD5282: 2 channels
- 256 positions
- +10 V to +15 V single supply;
±5.5 V dual-supply operation - 20 kΩ, 50 kΩ, 200 kΩ fixed terminal resistance
- Low temperature coefficient:
30 ppm/°C - Power-on midscale preset1
- Programmable reset
- Operating temperature:
−40°C to +85°C - I2C-compatible interface
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 applica-tions, see the AD5260/AD5262 product information on www.analog.com
Applications
1 Assert shutdown and program the device during power-up, then deassert the shutdown to achieve the desired preset level.
2 The terms digital potentiometer, VR, and RDAC are used interchangeably.
