ولتاژ ورودی این ماژول شامل رنج 8 تا 24 ولت می باشد که باعث استفاده آسان تر این ماژول در کاربردهای مختلف خواهد شد (برای داشتن کیفیت توان و صدای مطلوب تر، ولتاژ ورودی توصیه شده بین 10 تا 24 ولت می باشد). از این کیت به عنوان یک تقویت کننده صوتی با کیفیت بسیار بالا می توان بهره برد. اگر از برق باتری اتومبیل برای منبع تغذیه استفاده می شود حتما باید فاقد نویز باشد و در صورت نیاز از ماژول کاهنده ولتاژ DC استفاده شود.
چیپ TPA3118 دارای ویژگی های محافظتی short-circuit ,over-voltage, under-voltage و overheating می باشد.
توصیه می شود در توان های بالاتر از هیت سینک استفاده کنید.
Description:
TPA3118 Mono Digital Audio Amplifier Module is a 60W single channel digital audio amplifier, which is based on the TPA3118 half-bridge and full-bridge audio amplifier chip. The TPA31xx series is a Class-D amplifier family without any filter circuit and AM, which has high efficiency of 90% with low power consumption. Due to low power dissipation, this series can be used without external heatsink under half load (60W/8Ω on the dual-layer PCBs) or with a small heatsink at a full load. The TPA3118 can operate as 2×30-W into an 8-Ω BTL Load at 24V supplying voltage (full load condition) or 1 × 60W in a mono full-bridge application (RL = 8 Ω) that is used as a mono amplifier in this amplifier board. This chip equipped with an internal protection circuit to protect it against short-circuit faults, over-voltage faults, under-voltage faults, DC input, and thermal faults (overheating).
This board can run one 4 ohms speaker or one 8ohms, which 8ohms speaker is the best selection to achieve continuous 60W output power. This module can be supplied with a wide range of 8V up to 26V that 24V with 2.5A is recommended. This amplifier board has 8 solder pad, 2 for supplying wires, 2 for connecting the speaker and 2 for feeding audio inputs, and 2 for jumpering to mute the output sound.
This tiny amplifier features powerful sound, high-quality sound, without POP noise, small to squeak, and large to cannon sound, that specially developed for applying in-home appliance and Portable Audio, such as flat panel television, flat-panel monitor, multimedia systems, wireless speakers, mini and microsystems, and home sound sets.
