AD5241

I2C® Compatible Digital Potentiometer

Manufactured by:

Product Details

The AD5241 and AD5242 provide a single-/dual-channel, 256-position, digitally controlled variable resistor (VR) device. These devices perform the same electronic adjustment function as a potentiometer, trimmer or variable resistor. Operating from single (+2.7 V to +5.5 V) or dual supplies (±2.7 V), these parts are ideal for applications in Communications, Multi-Media, Video and Audio equipment. Stable 30 ppm/°C, low noise settings result from internal SiCr thin film resistor technology used for the resistor segments. Internal power ON reset to midscale position speeds up initial circuit adjustment. Two programmable logic outputs are available to drive digital loads, gates, LED drivers, analog switches, etc. to save micro-controller pin usage. Additional package address decode pins allow multiple packages to share the same 2-wire I2C bus. Devices are available in the 1.1 mm thin TSSOP 14- and 16-lead packages.

EVAL-AD5242 Circuit Diagram

Product Details

The AD5242 supports single-supply 2.7 V to 5.5 V operation, making the device suitable for battery-powered applications and many applications requiring superior low temperature coefficient performance.

In addition, the AD5242 uses a versatile I2C-compatible 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-AD5242DBZ daughter board and the EVAL-MB-LV-SDZ motherboard can operate in single-supply mode and incorporate an internal power supply from the USB.

Complete specifications for the AD5242 can be found in the AD5242 data sheet.
