CAT5127集成電路（IC）的數(shù)字電位計(jì)規(guī)格書(shū)PDF中文資料

CAT5127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CAT5127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(lèi)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 CAT5127/CAT5129 are single digitally programmable potentiometers (DPP?) designed as a electronic replacement for mechanical potentiometers and trim pots. Ideal for automated adjustments on high volume production lines, they are also well suited for applications where equipment requiring periodic adjustment is either difficult to access or located in a hazardous or remote environment.

FEATURES

■ 32-position linear taper potentiometer

■ Non-volatile EEPROM wiper storage

■ Low standby current

■ Single supply operation: 2.5 V – 5.5 V

■ Increment Up/Down serial interface

■ Resistance values: 10 k?, 50 k? and 100 k?

■ CAT5127 in tiny 8-lead 2 mm x 2.5 mm TDFN and MSOP packages

■ CAT5129 in the 6-lead TSOT23 package

APPLICATION

■ Automated product calibration

■ Remote control adjustments

■ Offset, gain and zero control

■ Tamper-proof calibrations

■ Contrast, brightness and volume controls

■ Motor controls and feedback systems

■ Programmable analog functions
