CAT524WI-T2集成電路（IC）的數(shù)字電位計(jì)規(guī)格書(shū)PDF中文資料

CAT524WI-T2屬于集成電路（IC）的數(shù)字電位計(jì)。由安森美半導(dǎo)體公司制造生產(chǎn)的CAT524WI-T2數(shù)字電位計(jì)數(shù)字電位器是一系列集成電路器件，可提供類似于傳統(tǒng)機(jī)械電位器或變阻器的可調(diào)節(jié)電阻，但通過(guò)電子信號(hào)而非機(jī)械輸入來(lái)進(jìn)行控制。雖然這些器件的電阻可耗散的電能相對(duì)有限，但其電子控制能力有助于小型化、自動(dòng)化和遠(yuǎn)程控制信號(hào)級(jí)模擬電路，而這些電路本來(lái)可能會(huì)使用機(jī)械電位器。

DESCRIPTION

The CAT524 is a quad, 8-bit digitally-programmable potentiometer (DPP?) configured for programmable voltage and DAC-like applications. Intended for final calibration of products such as camcorders, fax machines and cellular telephones on automated high volume production lines, it is also well suited for selfcalibrating systems and for applications where equipment which requires periodic adjustment is either difficult to access or in a hazardous environment.

FEATURES

■ Four 8-bit DPPs configured as programmable voltage sources in DAC-like applications

■ Common reference inputs

■ Buffered wiper outputs

■ Non-volatile NVRAM memory wiper storage

■ Output voltage range includes both supply rails

■ 4 independently addressable buffered output wipers

■ 1 LSB accuracy, high resolution

■ Serial Microwire-like interface

■ Single supply operation: 2.7V - 5.5V

■ Setting read-back without effecting outputs

APPLICATIONS

■ Automated product calibration.

■ Remote control adjustment of equipment

■ Offset, gain and zero adjustments in self-calibrating and adaptive control systems.

■ Tamper-proof calibrations.

■ DAC (with memory) substitute
