AD5248: 256-Position Dual Channel I2C Compatible Digital Resistor
Product Description
The AD5248 provides a compact 3 mm x 4.9 mm packaged solution for dual 256 position adjustment applications. This device performs the same electronic adjustment function as a 2-terminal variable resistor.
Available in four different end-to-end resistance values (2.5 kΩ, 10 kΩ, 5 0kΩ, 100 kΩ) these low temperature coefficient devices are ideal for high accuracy and stability variable resistance adjustments. The wiper settings are controllable through the I2C compatible digital interface.
The resistance between the wiper and either end point of the fixed resistor varies linearly with respect to the digital code transferred into the RDAC latch.
In addition, two configurable address decode bits are available which enable up to four devices on one bus. This proves especially useful when different resistor values are desired on the same bus in order to optimize parameter settings/calibration.
Operating from a 2.7 to 5.5 volt power supply and consuming less than 5 µA allows for usage in portable battery operated applications. All parts are guaranteed to operate over the extended automotive temperature range of -40°C to +125°C.
