19-3562; Rev 1; 6/05 www.DataSheet4U.com 10-Bit, Dual, Nonvolatile, Linear-Taper Digital Potentiometers General Description The MAX5494–MAX5499 10-bit (1024-tap), dual, nonvolatile, linear-taper, programmable voltage-dividers and variable resistors perform the function of a mechanical potentiometer, but replace the mechanics with a 3-wire SPI™-compatible serial interface. The MAX5494/MAX5495 are dual, 3-terminal, programmable voltage-dividers; the MAX5496/MAX5497 are dual, 2-terminal variable resistors; and the MAX5498/ MAX5499 include one 2-terminal variable resistor and one 3-terminal programmable voltage-divider.
