The ADN2860 provides dual 512-position and a single 128position digitally controlled variable resistor1 (VR) in a single 4x4mm LFCSP package. This device performs 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. The fixed A-to-B terminal resistance of 25k or 250k has a 1% channel-to-channel matching tolerance and a nominal temperature coefficient of 35ppm/C.
