ADG1204 Low Capacitance, Low Charge Injection, ±15 V/+12 V, 4:1 iCMOS Multiplexer

02/22/2023

Product Details

The ADG1204 is a complementary metal-oxide semiconductor (CMOS) analog multiplexer, comprising four single channels designed on an iCMOS (industrial CMOS) process. iCMOS® is a modular manufacturing process that combines high voltage 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 previous 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 charge injection of this multiplexer makes it an ideal solution for data acquisition and sample-andhold applications, where low glitch and fast settling are required. Fast switching speed coupled with high signal bandwidth makes the device suitable for video signal switching. iCMOS construction ensures ultralow power dissipation, making the device ideally suited for portable and battery-powered instruments.

The ADG1204 switches one of four inputs to a common output, D, as determined by the 3-bit binary address lines: A0, A1, and EN. Logic 0 on the EN pin disables the device. 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. All switches exhibit break-before-make switching action.
