LPC661 General Description
`The LPC661 CMOS operational amplifier is ideal for operation from a single supply. It features a wide range of operating supply voltage from +5V to +15V, rail-to-rail output swing and 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 kW and 5 kW) are all equal to or better than widely accepted bipolar equivalents, while the supply current requirement is typically 55 A.
`This chip is built with National's advanced Double-Poly Silicon-Gate CMOS process.
`See the LPC660 datasheet for a Quad CMOS operational amplifier or the LPC662 data sheet for a Dual CMOS operational amplifier with these same features.
