256 Position I2C Compatible Digital Potentiometer
The AD5245 provides a compact 2.9 mm x 3 mm packaged solution for 256 position adjustment applications. This device performs the same electronic adjustment function as a mechanical potentiometer or a variable resistor. The low temperature coefficient makes this device ideal for high accuracy and stability variable resistance adjustments.
The wiper settings are controllable through the I2C compatible digital interface, which can also be used to read back the present wiper register control word.
Operating from a 2.7 to 5.5 volt power supply consuming less than 5 µA allows for usage in portable battery operated applications.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
The AD5245 supports single-supply 2.7 V to 5.5 V operation, making the device suitable for battery-powered applications and many applications requiring superior low temperature coefficient performance.
In addition, the AD5245 uses a versatile I2C-compatible serial interface that operates in fast mode, allowing speeds of up to 400 kHz. This interface can be used to read back the wiper register.
The EVAL-AD5245DBZ daughter board and the EVAL-MB-LV-SDZ motherboard can operate in single-supply mode and incorporate an internal power supply from the USB.
Complete specifications for the AD5245 can be found in the AD5245 data sheet.
