AD5203ARUZ100: 4-Channel, 64-Position Digital Potentiometer TSSOP-24封装
The AD5203 contains four, 64-position digitally-controlled variable resistors (VR). These parts 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. The fixed A to B terminal resistance of 10K ohm, or 100K ohm has a ±1% channel-to-channel matching tolerance with a nominal temperature coefficient of 700 ppm/°C.
Wiper position programming defaults to midscale at system power ON when using the RS pin. Once powered the wiper position is programmed by a standard SPI, Microwire compatible serial data interface. In addition, a serial data output pin is available to daisy chain multiple packages to minimize the number of package-decode pins required from the system micro controller.
The AD5203 is available in a 24-lead narrow-body plastic DIP, the 24 lead surface mount package, and the compact 1.1mm thin TSSOP-24 package. All parts are guaranteed to operate over the extended-industrial-temperature range of -40°C to +85°C.
