DS1803Z-100 Description

Short technical summary and product information.

The DS1803Z-100 is an addressable dual digital potentiometer from Analog Devices / Maxim Integrated, offering two independently controlled 256-position potentiometers. It operates with a supply voltage range of 2.7V to 5.5V and features a standard resistance value of 100kΩ with linear taper.

 

Device control is achieved through a 2-wire serial interface, allowing up to 8 DS1803 devices to share the same interface using three address pins. The exact wiper position of each potentiometer can be written or read. The device is specified for an industrial operating temperature range of -40°C to +85°C.

 

This component is available in a 16-pin SOIC surface-mount package. It is a volatile device, meaning wiper positions are reset to the low-end terminals upon power loss. The DS1803Z-100 is suitable for applications requiring digitally controlled resistance or voltage division.
