EVAL-ADG1634LEBZ屬于開發(fā)板套件編程器的評估演示板及套件。由亞德諾半導體技術有限公司制造生產的EVAL-ADG1634LEBZ評估和演示板及套件該系列產品提供了一種方便的方法，在經(jīng)過驗證的實施環(huán)境中評估某些重點器件的性能或特性。評估方法通常有完善的文檔說明，并且視乎具體情況由評估軟件提供支持。產品通常由印刷電路板組成，板上已裝有重點器件以及必要或有用的支持元器件，另外也可能包括其他組件，例如電纜或電源。對于數(shù)量特別多或類別獨特的器件類別(如 ADC、DAC 和開關模式電源)，評估平臺可組合為一個單獨的產品系列。

GENERAL DESCRIPTION

The ADG1634L is a monolithic industrial CMOS (iCMOS?) analog

switch comprising four independently selectable single-pole, double-

throw (SPDT) switches, respectively.

All channels exhibit break-before-make switching action that prevents

momentary shorting when switching channels. An EN input

on the ADG1634L is used to enable or disable the device. When

disabled, all channels are switched off. The switch is enabled with a

Logic 1 EN input, while the INx input defines the state of the SPDT

switch (see Table 12).

The ultralow on resistance and on-resistance flatness of the switch

makes it an ideal solution for data acquisition and gain switching

applications, where low distortion is critical. iCMOS construction

ensures ultra low power dissipation, making the device ideally

suited for portable and battery-powered instruments.

An external VL supply provides flexibility for lower logic control. The

ADG1634L is both 1.2 V and 1.8 V JEDEC standard compliant.
