The AD202 is a general purpose, two-port, transformer-coupled isolation amplifier that may be used in a broad range of applications where input signals must be measured, processed and/or transmitted without a galvanic connection. This industry standard isolation amplifier offers a complete isolation function, with both signal and power isolation provided for in a single compact plastic SIP or DIP style package. The AD202 is powered directly from a +15 V dc supply.The AD202 provides total galvanic isolation between the input and output stages of the isolation amplifier through the use of internal transformer-coupling. The functionally complete AD202 eliminates the need for an external, user-supplied dc/dc converter. This permits the designer to minimize the necessary circuit overhead and consequently reduce the overall design and component costs.The design of the AD202 emphasizes maximum flexibility and ease of use, including the availability of an uncommitted op amp on the input stage. They feature a bipolar ±5 V output range, an adjustable gain range of from 1 to 100 V/V, ±0.025% max nonlinearity (K grade), 130 dB of CMR.Applications Multichannel Data Acquisition Current Shunt Measurements Motor Controls Process Signal Isolation High Voltage Instrumentation Amplifier

The AD5162 provides a compact 3 mm × 4.9 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 kΩ, 10 kΩ, 50 kΩ, 100 kΩ), 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 µA 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 AD5204/AD5206 provide 4-/6-channel, 256-position digitally controlled variable resistor (VR) devices. These devices perform the same electronic adjustment function as a potentiometer or variable resistor. Each channel of the AD5204/AD5206 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 endpoint 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 10 kΩ, 50 kΩ, or 100 kΩ has a nominal temperature coefficient of 700 ppm/°C.Each VR has its own VR latch that holds its programmed resistance value. These VR latches are updated from an internal serial-to-parallel shift register that is loaded from a standard 3-wire serial-input digital interface. Eleven data bits make up the data-word clocked into the serial input register. The first three bits are decoded to determine which VR latch is loaded with the last eight bits of the data-word when the CS strobe is returned to logic high. A serial data output pin at the opposite end of the serial register (AD5204 only) allows simple daisy chaining in multiple VR applications without requiring additional external decoding logic.An optional reset (PR) pin forces all the AD5204 wipers to the midscale position by loading 0x80 into the VR latch.The AD5204/AD5206 are available in the 24-lead surface-mount SOIC and TSSOP packages. The AD5204 is also available in a 32-lead, 5 mm × 5 mm LFCSP package. All parts are guaranteed to operate over the extended industrial temperature range of −40°C to +85°C.
