ANALOG DEVICES 256-Position Two-Time Programmable I 2 C Digital Potentiometer AD5170 handbook (1)(1)
The document describes the AD5170 as a 256-position, two-time programmable (TTP) digital potentiometer that utilizes fuse link technology for permanent programming. It offers unlimited adjustments before one-time programming (OTP) activation and includes a unique temporary OTP overwrite feature allowing new settings after the fuse is blown.
The device supports end-to-end resistance values of 2.5 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ in an MSOP-10 package. Key features include a low temperature coefficient of 35 ppm/°C, fast settling time, and operation within a single-supply range of 2.7 V to 5.5 V.
