Manufactured on iCMOS high-voltage industrial-process technology, the AD8663 is a 16V precision, low-noise, rail-to-rail operational amplifier. It addresses the performance, power and cost requirements of portable and battery-operated applications, such as patient monitors, defibrillators, remote industrial controls and optical sensors. These types of higher voltage portable devices are increasingly adopting lithium-ion, lithium-polymer and other batteries operating in 3 to 16V ranges. The device incorporates patented DigiTrim in-circuit trimming technology to achieve low offset voltage, 90dB common-mode rejection ratio, and 105dB power-supply rejection ratio.
