Overview
The ADG723BRMZ-REEL7, produced by Analog Devices Inc., is a CMOS, low-voltage, dual SPST (Single-Pole Single-Throw) analog switch. This device is part of the ADG721, ADG722, and ADG723 family, which are designed to operate from a single supply voltage ranging from 1.8 V to 5.5 V. This makes them highly suitable for use in battery-powered instruments and applications requiring low power consumption and high performance.
The ADG723BRMZ-REEL7 is packaged in an 8-lead MSOP (Mini Small Outline Package), which is ideal for space-constrained applications. Each switch in the ADG723 conducts equally well in both directions when on, and the device exhibits break-before-make switching action.
