1.Due to the difference between different monitors,there are color differences,pls understand.
2.Please allow 1-3mm errors due to manual measurement.
TPA3118 digital amplifier board is the use of the United States TI’s TPA3118D2 high-performance amplifier chip, beyond the TPA3123 chip. DC single power supply, wide operating voltage 6-25V power supply, the largest 25W +25 W two-channel output, parallel bridging (PBTL) 50W mono output.
TPDA3118 This board design is mainly practical, small size (59.76×54.1mm), wide operating voltage (6-25V), the output power (greater than 25W +25 W double channel), fever, efficiency up to 90% Sound quality is also good.
Most of the parts is the use of high stability of the SMD patch, performance is common hand inserts can not be compared. Filter capacitor using nichicon ELNA and other audio-specific capacitors, with switch-Taiwan-produced potentiometer, with power LED display, the use of more convenient. With 3.5MM standard audio input socket; also equipped with 3P socket from the “Lin” “G” “Rin” audio input, modified amplifier more convenient. Board standby SD standby control MUTE control is very convenient with other boards support parallel bridge (PBTL) 50W mono output. All products are in-kind shooting.
Basic parameters :
Board size ——— 59.76 * 54.1MM (not including potentiometer protruding part 15MM)
Operating voltage range —- 6 – 25V (power supply current should be greater than 2A, more power to more than 3A current)
Speaker impedance ——– 4 – 8 ohms
The maximum output power — 25W / 4 Europe +25 W / 4 Europe
Output power: (Speaker recommendations: power is less than 20V available 4-8 Europe, more than 20V with 8 Europe)
TIP: Sufficient output power will be available if the audio input is sufficient and the supply voltage / current is sufficient. Higher power supply voltage will be greater relative power, different impedance of the speaker will have different output power.
12W (left channel) + 12W (right channel), 4 European speakers / greater than 18 +18 W,
15V ——- 8 Europe / 18 + 18W, 4 Europe / greater than 22 +22 W,
19V ——- 8 Europe / 25 +25 W, 4 Europe / greater than 28 +28 W,
22-24V — 8 Europe / greater than 28 +28 W,
Parallel bridge Mono output power: (and monaural speaker selection recommendations: power is less than 20V available 3-4 Europe, more than 20V with 8 Europe)
Power supply voltage: 12V ——- 3 European speakers / 30W, 4 Europe / 25W,
15V ——- 3 Europe / greater than 43 W, 4 Europe / greater than 35W,
19V ——- 3 Europe / greater than 60W, 4 Europe / greater than 50W,
22-24V — 8 Europe / greater than 45W
