| 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.

Vp = 16 V; RI. = 8 Q; Tamb = 25 C; f =1 kHz; symmetrical power supply IMUTE < 30 [LIA. SEE Fig.4 2. The power bandwidth is measured at an output power of PQ max -3 dB 3. The noise output voltage (RMS value) is measured at Rg = 2 kl2, unweighted (20 Hz to 20 kHz) 4. The ripple rejection is measured at Rs = 0 and f = 100 Hz to 20 kHz. The ripple voltage (200 mV) is applied in phase to the positive and the negative supply rails'. With asymmetrical power supplies, the ripple rejection is'measured at f = 1 kHz 5. Vp = 4 V; RL =* 8 Q; Tamb = 25 C; f =1 kHz; symmetrical power supply. See Fig.4 6. Vp = 24 V; R)_ = 8 Q; Tamb = 25 C; f =1 kHz; asymmetrical power supply IMUTE < 30 )LIA. See Fig.5 7. 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 |
