RENESAS R2A15112
R2A15112FP is a Digital Power Amplifier IC developed for TV.
R2A15112FP has a maximum power of 15W(typ)
×
2ch.
(VD = 24V,THD = 1%, SE) at a 4
Ω
load.
It is possible to replace a conventional analog amplifier
with a digital amplifier easily.
●
Maximum power out put (No external heat sink)
(note) These apply when the thermal pad is soldered to
the printed-circuit board directly.
