ИС, цифровые потенциометры MAX5488EUD+

Энергонезависимый цифровой потенциометр , 50 кОм, Двойной, SPI, Линейный, ± 25%, 2.7 В

The MAX5488EUD+ from Maxim Integrated Products is a dual, non-volatile, SPI interface, linear taper digital potentiometer in 14 pin TSSOP package. This digital potentiometers function as mechanical potentiometer with a simple 3-wire SPI compatible digital interface that programs the wipers to any one of 256 tap positions. Wiper position stored in non-volatile memory (EEPROM) and recalled upon power-up or recalled by an interface command. It features a non volatile memory (EEPROM) to return the wipers to their previously stored positions upon power-up. The MAX5488 has end to end resistance of 50Kohm. This device has a low 35ppm/°C end to end temperature coefficient and operates from a single +2.7V to +5.25V supply. Typical applications include LCD screen adjustment, audio volume control, mechanical potentiometer replacement, low drift programmable filters and low drift programmable gain amplifiers.
