ILA2616
1
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
Requires very few external components
No switch-on/switch-off clicks
Input mute during switch-on and switch-off
Low offset voltage between output and
ground
Excellent gain balance of both amplifiers
Hi-fi in accordance with IEC 268 and DIN 45500
Short-circuit proof and thermal protected
Mute possibility.

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

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.
