DS1669S-10+ Information

Description

The DS1669S-10+ is a nonvolatile digital potentiometer from Analog Devices, offering 256 positions with nonvolatile storage for resistance values. It can be controlled via a simple 2-wire serial interface and operates on a single supply voltage from 2.7V to 5.5V, providing resistance values from 10kΩ to 50kΩ. The device features EEPROM memory for storing resistance values. This digital potentiometer is commonly used in various applications such as audio equipment for volume control, LCD monitors for brightness adjustment, industrial control systems for setting parameters, and instrumentation and test equipment for calibration and signal conditioning.

Features

According to the product information, the features of the DS1669S-10+ are:

Digital potentiometer IC with 256 positions
Nonvolatile storage for resistance values
Controlled via a simple 2-wire serial interface
Operates on a single supply voltage from 2.7V to 5.5V
