MAX547 : The MAX547 contains eight 13-bit, voltage-output digital-toanalog converters (DACs). On-chip precision output amplifiers provide the voltage outputs. The MAX547 operates from a ±5V supply. Bipolar output voltages with up to ±4.5V voltage swing can be achieved with no external components. The MAX547 has four separate reference inputs; each is connected to two DACs, providing different fullscale output voltages for every DAC pair. The MAX547 features double-buffered interface logic with a 13-bit parallel data bus. Each DAC has an input latch and a DAC latch. Data in the DAC latch sets the output voltage. The eight input latches are addressed with three address lines. Data is loaded to the inpu.

MAX5471 : The MAX5471/MAX5472/MAX5474/MAX5475 lineartaper digital potentiometers function as mechanical potentiometers, but replace the mechanics with a simple 3-wire up/down digital interface.

MAX5477 : The MAX5477/MAX5478/MAX5479 nonvolatile, dual, linear-taper, digital potentiometers perform the function of a mechanical potentiometer, but replace the mechanics with a simple 2-wire digital interface. Each device performs the same function as a discrete potentiometer or variable resistor and has 256 tap points. The devices feature an internal, nonvolatile EEPROM used to store the wiper position for initialization during power-up. A write-protect feature prevents accidental overwrites of the EEPROM. The fast-mode I2C-compatible serial interface allows communication at data rates up to 400kbps, minimizing board space and reducing interconnection complexity in many applications. Three address .
