GENERAL DESCRIPTION

The ADG1206 and ADG1207 are monolithic iCMOS® analog

multiplexers comprising sixteen single channels and eight

differential channels, respectively. The ADG1206 switches one

of sixteen inputs to a common output, as determined by the

4-bit binary address lines A0, A1, A2, and A3. The ADG1207

switches one of eight differential inputs to a common differential

output, as determined by the 3-bit binary address lines A0, A1,

and A2. An EN input on both devices is used to enable or disable

the device. When disabled, all channels are switched off. When

on, each channel conducts equally well in both directions and

has an input signal range that extends to the supplies.

The industrial CMOS (iCMOS) modular manufacturing

process combines high voltage, complementary metal-oxide

semiconductor (CMOS) and bipolar technologies. It enables the

development of a wide range of high performance analog ICs

capable of 33 V operation in a footprint that no other generation

of high voltage devices has been able to achieve. Unlike analog

ICs using conventional CMOS processes, iCMOS components

can tolerate high supply voltages while providing increased

performance, dramatically lower power consumption, and

reduced package size.

The ultralow capacitance and exceptionally low charge injection

of these multiplexers make them ideal solutions for data acquisition

and sample-and-hold applications, where low glitch and fast

settling are required. Figure 2 shows that there is minimum

charge injection over the entire signal range of the device.

iCMOS construction also ensures ultralow power dissipation,

making the devices ideally suited for portable and battery-

powered instruments.
