DS1845E-050 Description

Short technical summary and product information.

The DS1845E-050 from Analog Devices is a dual non-volatile digital potentiometer and memory device. It integrates two linear taper potentiometers: one 100-position and one 256-position, along with 256 bytes of EEPROM memory.

 

This device features an I2C compatible 2-wire interface for accessing data and controlling potentiometer wiper settings. The EEPROM can store configuration or calibration data, and wiper positions can be non-volatilely stored. A Write Protect (WP) pin is available to protect both memory and potentiometer settings from accidental changes.

 

Designed for applications requiring precise bias voltage and current control, the DS1845E-050 operates from a supply voltage range of 2.7V to 5.5V. It has a nominal resistance of 50k ohms with a tolerance of ±20% and a temperature coefficient of 750ppm/°C typical. The operating temperature range is -40°C to +85°C.

 

Available in a 14-TSSOP package, this digital potentiometer is suitable for surface mount applications. Up to eight DS1845 devices can be connected on a single 2-wire bus, with device addressing determined by A0-A2 pins.
