The AD5162 provides a compact 3 mm נ4.9 mm packaged solution for dual 256 position adjustment applications. This device performs the same electronic adjustment function as a 3-terminal mechanical potentiometer.Available in four different end-to-end resistance values (2.5 k?, 10 k?, 50 k?, 100 k?), this low temperature coefficient device is ideal for high accuracy and stability-variable resistance adjustments.The wiper settings are controllable through the SPI compatible digital interface. The resistance between the wiper and either end point of the fixed resistor varies linearly with respect to the digital code transferred into the RDAC latch.Operating from a 2.7 V to 5.5 V power supply and consuming less than 6 ?A allows the AD5162 to be used in portable battery-operated applications.For applications that program the AD5162 at the factory, Analog Devices offers device programming software running on Windows? NT/2000/XP operating systems. This software effectively replaces the need for external SPI controllers, which in turn enhances the time to market of systems. An AD5162 evaluation kit and software are available. The kit includes a cable and instruction manual.APPLICATIONS Systems calibrations Electronics level settings Mechanical trimmers replacement in new designs Permanent factory PCB setting Transducer adjustment of pressure, temperature, position, chemical, and optical sensors RF amplifier biasing Automotive electronics adjustment Gain control and offset adjustment

The AD5165 provides a compact 2.9 mm ? 2.8 mm packaged solution for 256-position adjustment applications. These devices perform the same electronic adjustment function as mechanical potentiometers or variable resistors, with enhanced resolution, solid-state reliability, and superior low temperature coefficient performance. The AD5165?s supply voltage requirement is 2.7 V to 5.5 V, but its logic voltage requirement is 1.8 V to VDD. The AD5165 consumes very low quiescent power during standby mode and is ideal for battery-operated applications.Wiper settings are controlled through a simple 3-wire interface. The interface is similar to the SPI? digital interface except for the inverted chip-select function that minimizes logic power consumption in the idling state. The resistance between the wiper and either endpoint of the fixed resistor varies linearly with respect to the digital code transferred into the wiper register.Operating from a 2.7 V to 5.5 V power supply and consuming less than 50 nA typical standby power allows use in battery-operated portable or remote utility device applications.Note: The terms digital potentiometer, RDAC, and VR are used interchangeably.APPLICATIONS Battery-operated electronics adjustment Remote utilities meter adjustment Mechanical potentiometer replacement Transducer circuit adjustment Automotive electronics adjustment Gain control and offset adjustment System calibration VCXO adjustment

The AD5228 is Analog Devices? latest 32-step-up/step-down control digital potentiometer emulating mechanical potentiometer operation. Its simple up/down control interface allows manual control with just two external pushbutton tactile switches. The AD5228 is designed with a built-in adaptive debouncer that ignores invalid bounces due to contact bounce commonly found in mechanical switches. The debouncer is adaptive, accommodating a variety of pushbutton tactile switches that generally have less than 10 ms of bounce time during contact closures. When choosing the switch, the user should consult the timing specification of the switch to ensure its suitability in an AD5228 application.The AD5228 can increment or decrement the resistance in discrete steps or in autoscan mode. When the PU or PD button is pressed briefly (no longer than 0.6 s), the resistance of the AD5228 changes by one step. When the PU or PD button is held continuously for more than a second, the device activates the autoscan mode and changes four resistance steps per second.The AD5228 can also be controlled digitally; its up/down features simplify microcontroller usage. The AD5228 is available in a compact thin SOT-23-8 (TSOT-8) package. The part is guaranteed to operate over the automotive temperature range of ?40?C to +105?C.The AD5228?s simple interface, small footprint, and very low cost enable it to replace mechanical potentiometers and trimmers with typically 3? improved resolution, solid-state reliability, and faster adjustment, resulting in considerable cost saving in end users? systems.Users who consider EEMEM potentiometers should refer to the recommendations in the Applications section.APPLICATIONS Mechanical potentiometer and trimmer replacements LCD backlight, contrast, and brightness controls Digital volume control Portable device-level adjustments Electronic front panel-level controls Programmable power supply

The AD5233 is a quad-channel nonvolatile memory,1 digitally controlled potentiometer2 with a 64-step resolution. The device performs the same electronic adjustment function as a mechanical potentiometer with enhanced resolution, solid-state reliability, and remote controllability. The AD5233 has versatile programming using a serial peripheral interface (SPI) for 16 modes of operation and adjustment, including scratchpad programming, memory storing and restoring, increment/decrement, ?6 dB/step log taper adjustment, wiper setting readback, and extra EEMEM for user-defined information such as memory data for other components, look-up tables, or system identification information.In the scratchpad programming mode, a specific setting can be programmed directly to the RDAC register, which sets the resistance between Terminal W to Terminal A and Terminal W to Terminal B. This setting can be stored into the EEMEM and is transferred automatically to the RDAC register during system power-on.The EEMEM content can be restored dynamically or through external PR strobing. A WP function protects EEMEM contents. To simplify the programming, independent or simultaneous increment or decrement commands can be used to move the RDAC wiper up or down, one step at a time. For logarithmic ?6 dB step changes in wiper settings, the left or right bit shift command can be used to double or halve the RDAC wiper setting.The AD5233 is available in a thin 24-lead TSSOP package. The part is 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 Programmable power supply Sensor calibration
