FUNCTIONAL DESCRIPTION
The ILA7056SH is a mono output amplifier, designed for battery-fed portable radios and mains-fed equipment such as
television. For space reasons there is a trend to decrease the number of external components. For portable applications there
is also a trend to decrease the number of battery cells, but still a reasonable output power is required.
The ILA7056SH fulfills both of these requirements. It needs no peripheral components, because it makes use of the Bridge-
Tied-Load (BTL) principle. Consequently it has, at the same supply voltage, a higher output power compared to a conventional
Single Ended output stage. It delivers an output power of 1 W into a loudspeaker load of 8 W with 6 V supply or 3 W into 16 W
loudspeaker at 11 V without need of an external heatsink. The gain is internally fixed at 40 dB. Special attention is given to
switch-on/off click suppression, and it has a good overall stability. The load can be short circuited at all input conditions.

POWER DISSIPATION
Assume: VP = 11 V; RL = 16 W.
The maximum sine-wave dissipation is 1.52 W.
The Rth j-a of the package is 55 K/W.
Tamb max = 150 - 55 ´ 1.52 = 66.4 °C.
