MAX5483EUD+

MAX5483EUD+ is a 10bit (1024-tap) non-volatile, linear-taper, programmable voltage-divider and variable resistor perform the function of a mechanical potentiometer, but replace the mechanics with a pin configurable 3-wire serial SPI™-compatible interface or up/down digital interface. It feature an internal, non-volatile EEPROM that stores the wiper position for initialization during power-up. The 3-wire SPI-compatible serial interface allows communication at data rates up to 7MHz. A pin-selectable up/down digital interface is also available. Ideal for applications requiring digitally controlled potentiometers. The nominal resistor temperature coefficient is 35ppm/°C end-to-end, and only 5ppm/°C ratiometric, making this device ideal for applications requiring low-temperature-coefficient voltage-dividers, such as low-drift, programmable gain-amplifiers.

• 2-terminal variable resistors
