Микросхема DS1804Z-100+, Энергонезависимый подстроечный потенциометр, 100кОм

Характеристики

DS1804Z-100+, Энергонезависимый подстроечный потенциометр, 100кОмThe DS1804Z-100+ is a non-volatile trimmer potentiometer in 8 pin NSOIC package. The device provides an ideal method for low cost trimming applications using a CPU or manual control input with minimal external circuitry. Wiper position of the DS1804 can be stored in EEPROM memory and its position is manipulated by a three terminal port that provides an increment/decrement counter controlled interface. This port consists of the control inputs active-low CS, active-low INC and U/active-low D. On power-up, the DS1804 will load the value of EEPROM memory into the wiper position register or (1 of 100decoder). On power-down, the wiper position register data will be lost.
