AD5242BRUZ10
I2C-Compatible, 10kOhm 256-Position Digital Potentiometer, TSSOP16, Analog Devices, RoHS
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 kOm, 100 kOm, or 1 MOm 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.
