+15 V or ±5 V, Dual-Channel, SPI Compatible, 256 Position Digital Potentiometer
The AD5260 and AD5262 are 1- and 2-channel, 256 position, SPI interface digitally controlled, variable resistor (VR) devices. These parts operate from either a single +5 V to +15 V supply or a dual ±5 V supply, extending terminal voltage adjustment to these supply voltages. (Most industry digital potentiometers are limited to a 5 V operating range). These devices perform the same electronic adjustment function as a potentiometer or variable resistor while offering solid-state reliability and electronic packaging compactness. These devices are offered in the thin 1.1 mm height TSSOP 14- and 16-lead surface mount packages.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
We are using AD5262 Digital Potentiometer to generate -1.5V using LT3015 LDO. VDD=5V, VSS=-5V, VL=3.3V. This Potentiometer is used in the place of top resistor in feedback resistor network. Output of LDO is connected to Wiper terminal in 2nd channel and3 week(s) ago in Data Converters
