The AD5241 and AD5242 provide a single-/dual-channel, 256-position, digitally controlled variable resistor (VR) device. These devices perform the same electronic adjustment function as a potentiometer, trimmer or variable resistor. Operating from single (+2.7 V to +5.5 V) or dual supplies (±2.7 V), these parts are ideal for applications in Communications, Multi-Media, Video and Audio equipment. Stable 30 ppm/°C, low noise settings result from internal SiCr thin film resistor technology used for the resistor segments. Internal power ON reset to midscale position speeds up initial circuit adjustment. Two programmable logic outputs are available to drive digital loads, gates, LED drivers, analog switches, etc. to save micro-controller pin usage. Additional package address decode pins allow multiple packages to share the same 2-wire I2C bus. Devices are available in the 1.1 mm thin TSSOP 14- and 16-lead packages.
