DESCRIPTION The LS404 is a high performance quad operational amplifier with frequency and phase compensation built intothe chip. The internal phasecompensation allows stable operation as
voltage follower in spite of its high Gain-Bandwidth Product. The circuit presents very stable electrical characteristics over the entire supply
voltage range, and it particularly intended for professional and telecom applications (active filters, etc). The patented input stage circuit allows small input signal swings below the negative supply
voltage and prevents phase inversion when the inputs are over drivers. PIN CONNECTIONS (top view)
