1. outline
　　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.
2. feature
　●maximum power out put (no external heat sink)
　　　　(note) these apply when the thermal pad is soldered to
　　　　the printed-circuit board directly.
recommended power condition
se operation mode :15wx2ch(vd=24v,4ω load,thd+n:1%） 　
btl operation mode:30wx1ch(vd=21v,8ω load,thd+n:10%）
●highly efficient, low noise, and low distortion
●popless
●built-in protection - overcurrent, overheat, and undervoltage
●built-in mute and standby function
●the gain can be changed to four settings by two terminals.
3. recommended operating conditions
　●power supply voltage : 11v to 25v
　●speaker impedance : from 4 to 8ω
