Nonvolatile, I2C®-Compatible 64-Position, Digital Potentiometer

Manufactured by:

Product Details

The AD5258 provides a compact, nonvolatile 3 mm × 4.9 mm packaged solution for 64-position adjustment applications. These devices perform the same electronic adjustment function as mechanical potentiometers* or variable resistors, but with enhanced resolution and solid-state reliability.

The wiper settings are controllable through an I2C-compatible digital interface that is also used to read back the wiper register and EEPROM content in addition, resistor tolerance is stored within EEPROM, providing an end-to-end tolerance accuracy of 0.1%. There is also a software write protection function that ensures data cannot be written to the EEPROM register.

A separate VLOGIC pin delivers increased interface flexibility. For users who need multiple parts on one bus, Address Bit AD0 and Address Bit AD1 allow up to four devices on the same bus.

    Product Details

    The evaluation board for the AD5258 contains an SDP connection and software which allows the AD5258 to be controlled from an SDP board.

    This evaluation board requires an SDP Controller board for connection to the PC. The SDP controller board connects to the PC via USB 2.0. The evaluation board will connect to the SDP controller board. The evaluation board cannot be connected directly to the PC. The evaluation software running on the PC will communicate with the evaluation board through the SDP Controller board.

    The SDP Controller board is a separate list item in the ordering guide below (EVAL-SDP-CS1Z). If you have not previously purchased an SDP Controller board, please do so to ensure a full evaluation setup.
