Summary
[edit]DescriptionTPA3116-based subwoofer amplifier module 06 under test.jpg |
English: Class D audio power amplifier module based on the TPA3116D2 IC. This variant is a cheap Chinese product aimed at DIYers. This is a mono subwoofer amp with a front-end low-pass filter. Max power input is 25.5V DC, thus at a reasonably high supply of 24V DC the amp can provide around 46V peak-to-peak or 16V RMS output, corresponding to 32W into 8 Ohms or 64W into 4 Ohms. At either extreme, the amp runs reasonably cool and needs no forced ventilation. Needless to say, the vendors claim inflated power figures (although not outrageously inflated).
This photo shows the amp in the center, with a matching power supply on the right and a dummy 50W, 8Ohm load. Русский: Китайский модуль сабвуферного моно-усилителя на TPA3116. При питании от однополярного стабилизированного источника +24В выдаёт честных 32 Вт в 8 Ом и 64 не менее честных в 4 Ом. При этом мало греется, принудительный обдув не нужен. Качество звучания соответствует цене на али... На фото подопытный образец в центре, с подходящим блоком питания (справа) и нагрузкой (слева) |
