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.

Features and Benefits

  • Full-featured in conjunction with low voltage digiPOT motherboard (EVAL-MB-LV-SDZ)
  • Various test circuits
  • Various ac/dc input signals
  • PC control via a separately purchased system demonstration platform (SDP-B or SDP-S)
  • PC software for control

Product Detail

The AD5258 supports single-supply 2.7 V to 5.5 V operation, making the device suited for battery-powered applications and many other applications with superior low temperature coefficient performance.

In addition, the AD5258 uses a versatile I2C serial interface that operates in fast mode, allowing speeds of up to 400 kHz. This interface can be used to read back the wiper register and EEPROM content.

The EVAL-MB-LV-SDZ can operate in single-supply mode and incorporates an internal power supply from the USB.

Complete specifications for the AD5258 part can be found in the AD5258 data sheet.
