Analog Devices Introduces Advanced Circuits for Industrial and Instrumentation Applications

About ADI's iCMOS and iPolar Processes

The result of significant, multi-year R&D investments, both the iCMOS and iPolar processes enable a new category of high-performance analog components able to operate in electrically noisy, high-voltage environments such as process controls, factory automation systems, control loops, and other industrial electronic equipment.

The iCMOS process combines the performance benefits of a complementary bipolar process, the efficiency of CMOS (complementary metal oxide semiconductor) and high-voltage capability. Prior to this introduction, industrial designers considering an analog CMOS process were forced to add significant levels of signal conditioning, signal biasing and external op-amps to their systems. Under those conditions, manufacturing technologies capable of handling 30 V ranged up to 5.0 micron -- an order of magnitude greater than the 0.6-micron line widths achievable through iCMOS. ADI's iCMOS process is also able to fully isolate components from the substrate or each other, meaning that a single chip can mix-and-match 5-V CMOS with higher voltage 16-, 24- or 30-V CMOS circuitry, and with multiple voltage supplies running to the same chip.

The iPolar trench isolation process is a stable, high-voltage manufacturing methodology that replaces the bulky diffusion layers of traditional bipolar processes with a deep trench technique that dramatically increases transistor density and performance. This combination allows the development of products with significantly enhanced functionality while fitting into reduced package sizes. The iPolar process yields precision linear ICs that enhance analog signal processing, while the sub-micron 30-V iCMOS process is used to manufacture highly integrated mixed-signal devices. These new processes extend ADI's analog and mixed-signal circuit design breakthroughs into the high-voltage realm, giving industrial instrumentation customers access to the most advanced data converter, amplifier and sensor components.
