2 The ADG608 switches one of eight inputs to acommon output as determined by the 3-bit binary address linesA0, A1 and A2. The ADG609 switches one of four differentialinputs to a common differential output as determined by the2-bit binary address lines A0 and A1. An EN input on both de-vices is used to enable or disable the device. When disabled, allchannels are switched OFF. All the address and enable inputsare TTL compatible over the full specified operating tempera-ture range, making the parts suitable for bus-controlled systemssuch as data acquisition systems, process controls, avionics andATEs since the TTL compatible address inputs simplify the digitalinterface design and reduce the board space ADG608/ADG609 are designed on an enhanced LC2 MOSprocess that provides low power dissipation yet gives highswitching speed and low on resistance.

3 Each channel conductsequally well in both directions when ON and has an input signalrange which extends to the supplies. In the OFF condition, sig-nal levels up to the supplies are blocked. All channels exhibitbreak-before-make switching action preventing momentaryshorting when switching channels. Inherent in the design is lowcharge injection for minimum transients when switching thedigital ability to operate from single +3 V, +5 V or 5 V bipolarsupplies makes the ADG608 and ADG609 perfect for use inbattery operated instruments and with the new generation ofDACs and ADCs from Analog Devices. The use of 5 V sup-plies and reduced operating currents gives much lower powerdissipation than devices operating from 15 V HIGHLIGHTS1.
