DS1803Z-100+ Datasheet PDF - Maxim Integrated

●The DS1803Z-100+ is an addressable dual digital potentiometer in 16 pin NSOIC package. This IC features two independently controlled 256 position potentiometer and the device control is achieved through 2 wire serial interface. It has three address pins allow up to 8 DS1803"s to share the same 2 wire interface. The exact wiper position of each potentiometer can be written or read.

● Supply voltage range from 2.7V to 5.5V

● Operating temperature range from -40°C to 85°C

● Addressable using 3 address inputs

● Ultra low power consumption

● Two 8bit registers to set wiper position

● Data is transmitted most significant bit (MSB) first

● End to end resistance is 100Kohm at ±20% tolerance and temperature coefficient is 750ppm/°C

●DS1803 is a volatile device that does not maintain the position of the wiper during power-down or loss of power.
