For the first time in a TO-99 hermetically-sealed package: A commercially available FET-input operational amplifier with 5pA bias current, "zero" offset voltage, 5V/µs slew rate, same pin configuration and output characteristics as the popular AD741, and all at reasonable cost. Behind AD503L's success: Two happily-married chips, automatic laser trimming, clever circuit design, and Analog's Fourth Generation IC production facility. Read full article
