The 64-Position Up/Down Control Digital Potentiometer AD5227 is a low power digital potentiometer designed and manufactured by Analog Devices. It has three end-to-end terminal resistances of 10kΩ, 50kΩ and 100kΩ, and low temperature coefficient.
The AD5227 is a 64-step digital potentiometer designed to replace mechanical trimmers and potentiometers. It features a simple 3-wire up/down interface allowing manual or high-speed digital control with midscale presetting at power-up.
Available in 10 kΩ, 50 kΩ, and 100 kΩ end-to-end terminal resistance versions, the device operates over an automotive temperature range of -40°C to +105°C. It includes low potentiometer mode tempco (10 ppm/°C) and low rheostat mode tempco (35 ppm/°C), with ultralow power consumption.
