The AD5161 provides a compact 3 mm ? 4.9 mm packagedsolution for 256-position adjustment applications. Thesedevices perform the same electronic adjustment function asmechanical potentiometers or variable resistors, with enhancedresolution, solid-state reliability, and superior low temperaturecoefficient performance.The wiper settings are controllable through a pin selectable SPIor I2C compatible digital interface, which can also be used toread back the wiper register content. When the SPI mode isused, the device can be daisy-chained (SDO to SDI), allowingseveral parts to share the same control lines. In the I2C mode, address pin AD0 can be used to place up to two devices on thesame bus. In this same mode, command bits are available toreset the wiper position to midscale or to shut down the deviceinto a state of zero power consumption.Operating from a 2.7 V to 5.5 V power supply and consumingless than 5 ?A allows for usage in portable battery-operatedapplications.APPLICATIONS Mechanical potentiometer replacement in new designs Transducer adjustment of pressure, temperature, position, chemical, and optical sensors RF amplifier biasing Gain control and offset adjustment?

DC159A-A: Demo Board for the LT1425 Isolated Flyback Switching Regulators.

Demo circuit 1069A is a monolithic step-down switching regulator with LDO featuring LT3500. The demo circuit is designed for 5.0V and 3.3V outputs from a 6V to 36V input. The LDO output is configured as a post-regulator of the switching regulator output. The total current capability is up to 2A. The switching regulator can be synchronized to an external clock input or be resistor-programmed to a 250kHz to 2.2MHz internal oscillator. Programmable frequency allows for optimization between efficiency and external component size. Cycle-by-cycle current limit, frequency foldback and thermal shutdown provide protections against a shorted output. The soft-start feature controls the ramp rate of the output voltage, eliminates input current surge during startup, and also provides output tracking.
