●Product Details
●The AD5290 is one of the few high voltage, high performance, and compact digital potentiometers2, 3 in the market at present. This device can be used as a programmable resistor or resistor divider. The AD5290 performs the same electronic adjustment function as mechanical potentiometers, variable resistors, and trimmers, with enhanced resolution, solid-state reliability, and superior temperature stability.
●With digital rather than manual control, the AD5290 provides layout flexibility and allows closed-loop dynamic controllability.
●The AD5290 is available in MSOP-10 package and has 10 kΩ, 50 kΩ, and 100 kΩ options. All parts are guaranteed to operate over the –40°C to +125°C extended automotive temperature range.
●Applications
● High voltage DAC
● Programmable power supply
● Programmable gain and offset adjustment
● Programmable filters and delays
● Actuator control
● Audio volume control
● Mechanical potentiometer replacement
●1 iCMOS™ Process Technology. For analog systems designers who need high performance ICs at higher voltage levels, iCMOS is a technology platform that enables the development of analog ICs capable of 30 V and operating at ±15 V supplies while allowing dramatic reductions in power consumption and package size, and increased ac and dc performance.
●2 The terms digital potentiometer and RDAC are used interchangeably.
●3 The RDAC segmentation is protected by U.S. Patent Number 5,495,245.
