adg849 Summary of contents
Page 1
... Each switch of the ADG849 conducts equally well in both directions when on. The device exhibits break-before-make switching action, thus preventing momentary shorting when switching channels. The ADG849 is available in a tiny, 6-lead SC70 package, making it the ideal candidate for space-constrained applications. Rev. 0 Information furnished by Analog Devices is believed to be accurate and reliable. ...
