ILA2616 2 X 12 W HI-FI AUDIO POWER AMPLIFIERS WITH MUTE GENERAL DESCRIPTION The ILA2616 are dual power amplifiers. The ILA2616 is supplied in a 9-lead single-in-line (SIL9) plastic power package (SOT131). They have been especially designed for mains fed applications, such as stereo radio and stereo TV. FEATURES • Excellent gain balance of both amplifiers • Requires very few external components • Hi-fi in accordance with IEC 268 and DIN 45500 • No switch-on/switch-off clicks • Short-circuit proof and thermal protected • Input mute during switch-on and switch-off • Mute possibility. • Low offset voltage between output and ground QUICK REFERENCE DATA Stereo application SYMBOL PARAMETER CONDITIONS MIN.

The internal network at pin 2 is a resistor devider of typical 4 kQ and 5 kiltothe positive supply rail. At the connection of the 4 ki2 and 5 kQ resistor a zener diode of typical 6.6 V is also connected to the positive supply rail. The spread of the zener voltage is 6.1 to 7.1 V. 3
