Description

The AD5245BRJZ50-R2 provides a compact 2.9 mm × 3 mm packaged solution for 256-position adjustment applications. These devices perform the same electronic adjustment function as mechanical potentiometers or variable resistors, with enhanced resolution, solid-state reliability, and superior low temperature coefficient performance. The wiper settings are controllable through an I2 C-compatible digital interface, which can also be used to read back the wiper register content. AD0 can be used to place up to two devices on the same bus. Command bits are available to reset the wiper position to midscale or to shut down the device into a state of zero power consumption. AD5245BRJZ50-R2 Features •256-position •End-to-end resistance 5 kΩ, 10 kΩ, 50 kΩ, 100 kΩ •Compact SOT-23-8 (2.9 mm × 3 mm) package •Fast settling time: tS = 5 µs typ on power-up •Full read/writeof wiper register •Power-on preset to midscale •Extra package address decode pin AD0 •Computer software replaces µC in factory programming •Single supply: 2.7 V to 5.5 V •Low temperature coefficient 45 ppm/°C •Low power: IDD = 8 µA •Wide operating temperature: –40°Cto +125°C•Evaluation board available AD5245BRJZ50-R2 Applications •Mechanical potentiometer replacement in new designs •LCD panelVCOM adjustment•LCD panel brightness and contrast control •Transducer adjustment of pressure, temperature, position, •chemical, and optical sensors•RF amplifier biasing •Automotive electronics adjustment•Gain control and offset adjustment
