DESCRIPTION
The LS204 is a high performance dual 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 charac-
teristics over the entire supply voltage range, and
is particularlyintended for professional and telecom
applications (active filter, etc).
