LS204 Low-noise bipolar operational amplifier Datasheet - production data Description The LS204 is a low-noise bipolar operational amplifier with frequency and phase compensation built into the chip. The internal phase compensation allows stable operation as a D voltage follower in spite of its high gain-bandwidth SO-8 product. (Plastic micro package) The circuit presents very stable electrical characteristics over the entire supply voltage range and is particularly intended for professional Pin connections and telecom applications (such as active filtering).
