MCP4018T-103E/LT MICROCHIP Digital Potentiometers

The MCP4018T-103E/LT from Microchip is a 7‑bit single‑channel I²C digital potentiometer offering 128 taps and 10kΩ end‑to‑end resistance with ±20% tolerance, designed for compact precision‑resistance control and calibration. For selection, it operates across a 1.8–5.5V supply, draws 2.5µA typical static current, achieves a 1MHz –3dB bandwidth, and features a low 100Ω wiper resistance alongside a linear taper tailored for digitally‑adjusted voltage dividers, offset trimming, and bias tuning. In application, this potentiometer excels in DC‑DC converter feedback networks, LED‑lighting dimming control, portable‑device volume adjustment, industrial‑automation sensor calibration, and medical‑instrument offset nulling, while its AEC‑Q100‑qualified SC‑70‑6 package also enables space‑constrained automotive modules such as ambient‑light trimmers and HVAC actuator positioners.
