This guide describes the operation, characteristics, and applications of Analog Devices digital potentiometers, including CMOS architectures, memory…
The document introduces digital potentiometers as an alternative to mechanical ones, highlighting their use in microcontroller-based designs for dynamic control. It explains the underlying 'String DAC' architecture where A and B terminals connect to a reference voltage, and the wiper (W) acts as the output.
Specific product families are detailed, including volatile models like the AD5245 with various package types and resistance values, non-volatile E2MEM versions such as the dual-channel AD5235, and One-Time Programmable (OTP) devices like the AD5172/AD5173. The guide also covers precision options and AC performance considerations. This manual is written in Chinese.
The temperature coefficient is 35ppm/°C.
Options include Volatile, Nonvolatile E2MEM, One-Time Programmable (OTP), and Two-Time Programmable.
