Abstract
A monolithic operational amplifier is presented which optimizes voltage noise both in the audio frequency band, and in the low frequency instrumentation range. In addition, the design demonstrates that the requirements for low noise do not necessitate compromising the specifications in other respects. Techniques are set forth for combining low noise with high-speed and precision performance for the first time in a monolithic amplifier. Achieved results are: 3 nV//spl radic/Hz white noise, 80 nV/SUB p-p/ noise from 0.1 to 10 Hz, 17 V//spl mu/s slew rate, 63 MHz gain-bandwidth product, 10 /spl mu/V offset voltage, 0.2 /spl mu/V//spl deg/C drift with temperature, 0.2 /spl mu/V/month drift with time, and a voltage gain of two million.Keywords
