AD5242BRZ100-REEL7 digital potentiometer 100k Ohm 2 Circuit 256 Taps I²C Interface 16-SOIC
The AD5242BRZ100-REEL7 is a dual-channel, 256-position digital potentiometer from Analog Devices, designed as a high-reliability, software-controlled replacement for mechanical trimmers. This specific variant features a 100 kΩ nominal resistance per channel and is supplied in a 16-pin SOIC package with Tape & Reel (TR) packaging for automated assembly. It operates from a single 2.7 V to 5.5 V supply (or dual ±2.7 V) and communicates via a standard I²C serial interface (up to 400 kHz), supporting up to four devices on the same bus via address pins. A key feature is its 30 ppm/°C temperature coefficient and ±1% channel-to-channel matching, ensuring stable performance across the industrial temperature range of -40°C to +105°C. The device includes two auxiliary logic outputs for system control and features a power-on reset that defaults the wiper to mid-scale (position 128) for predictable startup behavior.
