- Extended temperature range: −40°C to +105°C
The AD5241/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. Each VR offers a completely programmable value of resistance between the A terminal and the wiper, or the B terminal and the wiper. For the AD5242, the fixed A-to-B terminal resistance of 10 kΩ, 100 kΩ, or 1 MΩ has a 1% channel-to-channel matching tolerance. The nominal temperature coefficient of both parts is 30 ppm/°C.
Wiper position programming defaults to midscale at system power on. When powered, the VR wiper position is programmed by an I2C-compatible, 2-wire serial data interface. Both parts have two extra programmable logic outputs available that enable users to drive digital loads, logic gates, LED drivers, and analog switches in their system.
The AD5241/AD5242 are available in surface-mount, 14-lead SOIC and 16-lead SOIC packages and, for ultracompact solutions, 14-lead TSSOP and 16-lead TSSOP packages. All parts are guaranteed to operate over the extended temperature range of −40°C to +105°C.

EVAL-AD5242
AD5242 Evaluation Board
Product Detail
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.
