GENERAL DESCRIPTION
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.
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.
