R2A15120FA 2chx 15W / 8ohm D-class power amplifier
General Description
R2A15120FA is standard IC of D-class power amplifier developed for FPD or Home audio etc.R2A15120FA can realize maximum Power 15W x 2ch (VD=15V,THD=10%,BTL) at 8Ωload.It is possible to construct the D-class amplifier system easily.
Features
Output Power 15W at RL=8Ω,VD=15V,THD=10%
(Note) Basically,it is necessary thermal-pad is connected to the board heat radiation part with solder.
Corresponding to analog differential/Single, PWM input.
Built-in the 2 channels(BTL)
Power supply voltage：Single power supply operation 11V to 25V recommendation
Built-in Over Current Protection, Over Temperature Protection,and Under Voltage Protection.
Built-in monitor terminal for protection mode.
Built-in protection circuit for prior warning of over temperature.
Settable power limit value of maximum output by external resistor.
Adjustable carrier frequency by external resistor.
Selectable gain value at four stage by setting two terminals. Package: 48 pins HTQFP(Body : 7x7mm Lead pitch: 0.5mm)
Note:This amplifier’s continuous maximum power is 15W/8ohm. As more than 15Wisoutput when VD is 24V, please control output power by changing power-limiter or gain diagram.
