ADG1422: 2.1 Ω Maximum On Res

ADG1422:  2.1 Ω Maximum On Resistance, ±15 V/+12/±5 V iCMOS Dual SPST Switches

The ADG1421/ADG1422/ADG1423 contain two independent single-pole/single-throw (SPST) switches. The ADG1421 and ADG1422 differ only in that the digital control logic is inverted. The ADG1421 switches are turned on with Logic 1 on the appropriate control input, and Logic 0 is required for the ADG1422. The ADG1423 has one switch with digital control logic similar to that of the ADG1421; the logic is inverted on the other switch. The ADG1423 exhibits break-before-make switching action for use in multiplexer applications. 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.

The iCMOS (industrial CMOS) 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 parts has achieved. 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 on resistance profile is very flat over the full analog input range ensuring excellent linearity and low distortion when switching audio signals. The iCMOS construction ensures ultralow power dissipation, making the part ideally suited for portable and battery-powered instruments.
