AD5243/AD5248 is a digital potentiometer from Analog Devices, with four resistance values of 2.5 kΩ, 10 kΩ, 50 kΩ and 100 kΩ, equipped with MSOP-10 package, single-supply power supply range of 2.7 V to 5.5 V, operating temperature range of −40°C to +125°C, and applications including system calibration, electronic level setting, mechanical trimmer replacement, permanent factory PCB setting, pressure, temperature, position, chemical and optical sensor transducer adjustment, and RF amplifier bias.
The AD5243 and AD5248 are dual‑channel, 256‑position digital potentiometers offered in four end‑to‑end resistance values (2.5 kΩ, 10 kΩ, 50 kΩ, 100 kΩ). They operate from a single 2.7 V to 5.5 V supply, consume less than 6 µA, and feature a low temperature coefficient of 35 ppm/°C. The devices are supplied in a compact MSOP‑10 (3 mm × 4.9 mm) package and include optional address‑decode pins for multi‑device I²C buses.
The datasheet contains sections on electrical and timing characteristics, absolute maximum ratings, pin descriptions, typical performance curves, programming instructions, evaluation board details, and ordering information. It also provides a wiring diagram, pin‑out figures, and a summary of key specifications for quick reference.
