Product Details

The AD5207 provides a dual channel, 256 position, digitally controlled variable resistor VR device. These devices perform the same electronic adjustment function as a potentiometer or variable resistor. Each channel of the AD5207 contains a fixed resistor with a wiper contact that taps the fixed resistor value at a point determined by a digital code loaded into the SPI compatible serial-input register. The resistance between the wiper and either end point of the fixed resistor varies linearly with respect to the digital code transferred into the VR latch. The variable resistor 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 10K, 50K or 100K ohms has a ±1% channel-to-channel matching tolerance with a nominal temperature coefficient of 500 ppm/°C. A unique switching circuit minimizes the high glitch inherent in traditional switched resistor designs and avoids any make-before-break or break-before-make operation. The AD5207 is available in 1.1 mm thin TSSOP-14 package, which is suitable for PCMCIA applications.
