Product Details

The ADG1201/ADG1202 are monolithic complementary metal-oxide semiconductor CMOS devices containing an SPST switch designed in an _i_CMOS® industrial CMOS process. _i_CMOS is a modular manufacturing process combining high voltage CMOS and bipolar technologies. It enables the development of a wide range of high perform- ance analog ICs capable of 33 V operation in a footprint that no previous generation of high voltage parts has been able to achieve. Unlike analog ICs using conventional CMOS processes, _i_CMOS components can tolerate high supply voltages while providing increased performance, dramatically lower power consumption, and reduced package size.

The ultralow capacitance and charge injection of these switches make them ideal solutions for data acquisition and sample-and-hold applications, where low glitch and fast settling are required. Fast switching speed coupled with high signal bandwidth make the parts suitable for video signal switching.

_i_CMOS construction ensures ultralow power dissipation, making the parts ideally suited for portable and battery- powered instruments. The ADG1201/ADG1202 contain a single-pole/single-throw SPST switch. Figure 1 shows that with a logic input of 1, the switch of the ADG1201 is closed and that of the ADG1202 is open. Each switch conducts equally well in both directions when on and has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked.
