HIGH PERFORMANCE

QUAD OPERATIONAL AMPLIFIERS

DESCRIPTION

The LS404is a high performancequadoperational
amplifier with frequency and phasecompensation
builtintothechip.Theinternalphasecompensation
allows stable operationas voltagefollowerin spite
of its high Gain-BandwidthProduct.

The circuit presents very stable electrical charac­teristics over the entire supply voltage range, and
it particularlyintendedforprofessionalandtelecom
applications(active filters, etc).

The patented input stage circuit allowssmall input
signal swings below the negative supply voltage
and preventsphase inversionwhen the inputs are
over drivers.
