AD5206 - 6-Channel Digital Potentiometers

General Description

Figure 2.

The AD5204/AD5206 provide 4-/6-channel, 256-position digitally controlled variable resistor (VR) devices.

These devices perform the same electronic adjustment function as a potentiometer or variable resistor.

Key Features

  • 256 positions.
  • Multiple independently programmable channels.
  • AD5204.
  • 4-channel.
  • AD5206.
  • 6-channel.
  • Potentiometer replacement.
  • Terminal resistance of 10 kΩ, 50 kΩ, 100 kΩ.
  • 3-wire SPI-compatible serial data input.
  • +2.7 V to +5.5 V single-supply operation; ±2.7 V dual-supply operation.
  • Power-on midscale preset.
