Name:3 channels bluetooth audio receiver amplifier board
Describe:
3 channels bluetooth audio receiver amplifier board
Content:
3 channels bluetooth audio receiver amplifier board
SL-A32 provide high-performance, thermally efficient amplifier solutions. it delivers 2x15W+15W into 8Ω loads. it is three channels amplifier ,one channel is L and R channel combined.with good sound.
it operate from a single 8V to 18V supply and provide a high 67dB PSRR, eliminating the need for a regulated power supply. They offer up to 90% efficiency from a 12V supply.
Both devices feature eight-digitally-controlled gain settings.
- Output Power: Maximum 2*15W+15W at RL=8Ω,VCC=18V
- Power efficiency is up to 90%
- Low Working Voltage Down To 8V, High Working Voltage up To 18V
- Thermal Protection function
- Output Pin Short-Circuit Protection
- Separate VCC & PVCC
- Class-D stereo audio design
- Components use SMT decal, the board dimension is very small
- IC decal is 36-TQFN
- No external heat-sink, Less heat, save heat sink cost
- The current is very small
- Mute function
- The PCB design provides both bead and LC solutions
