The ADN2860 provides dual 512-position and single 128-position, digitally controlled variable resistors1 (VR) in a single 4 mm x 4 mm 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 25 k or 250 k has a 1% channel-tochannel matching tolerance and a nominal temperature coefficient of 35 ppm/C.
