| Industry's Smallest SPI-Compatible, Dual 1024-Tap, Nonvolatile Digital Potentiometers Fit in 5mm x 5mm TQFN Package | |||||
SUNNYVALE, CA -Maxim Integrated Products introduces the MAX5494–MAX5499, the industry's smallest SPI™-compatible, dual 1024-tap, nonvolatile digital potentiometers available in a tiny 5mm x 5mm TQFN package. Integrated EEPROM simulates mechanical potentiometers by storing the wiper position prior to power down. This capability significantly reduces chip size compared to mechanical pots. The MAX549x digital pots also offer ratiometric and end-to-end temperature coefficients as low as 5ppm/°C and 35ppm/°C, respectively. The devices save power by requiring less than 1.5µA in standby and operating from a 2.7V to 5.25V single supply. End-to-end resistances of 10k and 50k are available. The MAX549x are offered in dual resistor-divider, dual variable resistor or resistor-divider/variable resistor configurations. An industry standard three-wire SPI serial interface makes these new digital pots simple to operate. | |||||
