The DS18030-050+ is an addressable dual digital potentiometer in 16 pin DIP 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 50Kohm 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.
