FUNCTIONAL BLOCK DIAGRAM

GENERAL DESCRIPTION

The AD5247 provides a compact, 2 mm × 2.1 mm, packaged solution for 128-position adjustment applications. This device performs the same electronic adjustment function as a mechanical potentiometer or a variable resistor. Available in four different end-to-end resistance values (5 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ), these low temperature coefficient devices are ideal for high accuracy and stability variable resistance adjustments. The wiper settings are controllable through the I2 C-compatible digital interface, which can also be used to read back the present wiper register control word. The 10 kΩ and 100 kΩ options each have three hard-coded slave address options available to allow users access to three of these devices on one I2 C bus (see Table 8 for a full list of slave address locations). 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. Note the terms digital potentiometer, VR (variable resistor), and RDAC are used interchangeably in this document. Operating from a 2.7 V to 5.5 V power supply and consuming 0.9 µA (3.3 V) allows the AD5247 to be used in portable battery-operated applications.
