The LPC660 CMOS Quad operational amplifier is ideal for operation from a single supply. It features a wide range of operating voltages from +5V to +15V and features rail-to-rail output swing in addition to an input common-mode range that includes ground. Performance limitations that have plagued CMOS amplifiers in the past are not a problem with this design. Input VOS, drift, and broadband noise as well as voltage gain (into 100 k and 5 k) are all equal to or better than widely accepted bipolar equivalents, while the power supply requirement is typically less than 1 mW. This chip is built with National's advanced Double-Poly Silicon-Gate CMOS process.
