AmplifierCircuits

General Description The TDA2611A is a monolithic integrated circuit in a 9-lead single in-line (SIL) plastic package with a high supply voltage  audio amplifier. Special features are:  possibility for increasing the input impedance  single in-line (SIL) construction for easy mounting  very suitable for application in mains-fed apparatus  extremely low number of external components  thermal protection  well defined open loop gain circuitry with simple quiescent current setting and fixed integrated closed loop gain.
