Philips Semiconductors Product specification
5 W audio power amplifier TDA2611A
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.
