Product Description

Product Details
The AD5222 contains two, 128-position, digitally-controlled variable resistors (VR). This part performs the same electronic adjustment function as a potentiometer, trimmer, or variable resistor. . The fixed A-to-B terminal resistance of 10 K, 50 K, 100 K, or 1 M Ohm has a 1% channel-to-channel matching tolerance with a nominal temperature coefficient of -300 ppm/°C. These products were optimized for portable instrument and test equipment "push button" applications.
The chip select CS, count CLK and U/D direction control inputs set the variable resistor position. A MODE control determines whether both VRs are incremented together or independently. With MODE at logic zero, both wipers are incremented UP or DOWN without changing the relative settings between the wipers. The relative ratio between the wipers is preserved if either wiper reaches the end of the resistor array. In the independent MODE (logic one) only the VR determined by the DACSEL pin is changed. This simple "push button" controlled interface eliminates the need for Micro Controllers in front panel interface designs.
The AD5222 is available in the surface mount (SO-14) package. For ultra compact solutions selected models are available in the thin TSSOP-14 package. All parts are guaranteed to operate over the extended industrial temperature range of -40°C to +85°C. For 3-wire, SPI compatible interface applications, see the AD5203/AD5206/AD7376/AD8400/AD8402/AD8403 products.
