DESCRIPTION
The TS512 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 products.
The circuit presents very stable electrical characteristics over the entire supply voltage range, and is particularlyintended for professional and telecom applications (active filter, etc).
