HIGH PERFORMANCE
DUALOPERATIONAL AMPLIFIERS
DESCRIPTION
The LS204is a highperformance dual operational
amplifier with frequency and phase compensation
builtintothechip.Theinternalphasecompensation
allows stable operation as voltagefollowerin spite
of itshigh Gain-BandwidthProduct.
The circuit presents very stable electrical characteristics over the entire supply voltage range, and
is particularlyintendedforprofessionalandtelecom
applications(activefilter, etc).
