16V Op Amps Enhance Consumer Apps

With an operating range from 5V to 16V, the AD8663 and AD8638 operational amplifiers suit an assortment of industrial, medical, and consumer applications. Both employ the company's proprietary iCMOS high-voltage industrial process technology. The AD8663 rail-to-rail op amp addresses the performance, power, and cost requirements of portable and battery-operated applications such as patient monitors, defibrillators, remote industrial controls, and optical sensors. The device specifies a CMRR of 90 db, PSRR of 105 dB, a maximum voltage offset drift of 450 µV at 125°C, low-frequency voltage noise at 21 nV/rt-Hz, and an operating current consumption of 180 µA. The AD8638 zero-drift op amp exhibits a 140-dB CMRR, 140-dB PSRR, 10-µV offset voltage over temperature, and a maximum offset drift of 80 nV/°C. Prices for the AD8663 and AD8638 range from$0.60 to $1.20 each/1,000. ANALOG DEVICES INC., Norwood, MA. (800) 262-5643.
