The AD5241 / AD52421 provide a single-/dual-channel, 256-position, digitally controlled variable resistor (VR) device. These devices 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. For the AD5242, the fixed A-to-B terminal resistance of 10 kΩ, 100 kΩ, or 1 MΩ has a 1% channel-to-channel matching tolerance. The nominal temperature coefficient of both parts is 30 ppm/°C.Wiper position programming defaults to midscale at system power on. When powered, the VR wiper position is programmed by an I2C-compatible, 2-wire serial data interface. Both parts have two extra programmable logic outputs available that enable users to drive digital loads, logic gates, LED drivers, and analog switches in their system.The AD5241 / AD5242 are available in surface-mount, 14-lead SOIC and 16-lead SOIC packages and, for ultracompact solutions, 14-lead TSSOP and 16-lead TSSOP packages. All parts are guaranteed to operate over the extended temperature range of −40°C to +105°C.APPLICATIONS Multimedia, video, and audio Communications Mechanical potentiometer replacement Instrumentation: gain, offset adjustment Programmable voltage-to-current conversion Line impedance matching

The AD5200 and AD5201 are programmable resistor devices, with 256 positions and 33 positions respectively, that can be digitally controlled through a 3-wire SPI serial interface. The terms programmable resistor, variable resistor (VR), and RDAC are commonly used interchangeably to refer to digital potentiometers. These devices perform the same electronic adjustment functionas a potentiometer or variable resistor. Both AD5200 / AD5201 contain a single variable resistor in the compact MSOP package. Each device contains a fixed wiper resistance at the wiper contact that taps the programmable resistance at a point determined by a digital code. The code is loaded in the serialinput register. The resistance between the wiper and either end point of the programmable resistor varies linearly with respect to the digital code transferred into the VR latch. Each 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 10 kΩ or 50 kΩ has a nominal temperature coefficient of 500 ppm/°C. The VR has a VR latch that holds its programmed resistance value. The VR latch is updated from an SPI-compatible serial-to-parallel shift register that is loaded from a standard 3-wire serial-input digital interface. Eight data bits for the AD5200 and six databits for the AD5201 make up the data word that is clocked into the serial input register. The internal preset forces the wiper to the midscale position by loading 80H and 10H into AD5200 and AD5201 VR latches respectively. The SHDN pin forces the resistor to an end-to-end open-circuit condition on the A terminal and shorts the wiper to the B terminal, achieving a microwatt power shutdown state. When SHDN is returned to logic high, the previous latch setting puts the wiper in the same resistance setting prior to shutdown. The digital interface is still active during shutdown so that code changes can be made that will produce a new wiper position when the device is returned from shutdown.All parts are guaranteed to operate over the extended industrial temperature range of –40°C to +85°C.APPLICATIONS Mechanical Potentiometer Replacement Instrumentation: Gain, Offset Adjustment Programmable Voltage to Current Conversion Programmable Filters, Delays, Time Constants Line Impedance Matching
