CAT525集成電路（IC）的數(shù)字電位計規(guī)格書PDF中文資料

CAT525屬于集成電路（IC）的數(shù)字電位計。由安森美半導(dǎo)體公司制造生產(chǎn)的CAT525數(shù)字電位計數(shù)字電位器是一系列集成電路器件，可提供類似于傳統(tǒng)機械電位器或變阻器的可調(diào)節(jié)電阻，但通過電子信號而非機械輸入來進行控制。雖然這些器件的電阻可耗散的電能相對有限，但其電子控制能力有助于小型化、自動化和遠程控制信號級模擬電路，而這些電路本來可能會使用機械電位器。

DESCRIPTION

The CAT525 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 and systems capable of self calibration, it is also well suited for applications were equipment requiring periodic adjustment is either difficult to access or located in a hazardous environment.

FEATURES

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

■ Independent 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
