TICore400M TPA3255 PBTL Mono Single Supply 48V RTR Amplifier Module
TPA3255 based, mono class-D amplifier with 2 ohms load capability.
The board has a passive PFFB configuration from slaa788a. PFFB can be enabled/disabled by the user through onboard jumpers.
The analog input can accept full balanced or single ended signals which can be configured by onboard jumpers. The output is 1 channel, mono PBTL configuration.
Includes TVS diode for power supply surge protection, and will normally fail short when an accidental reverse polarity is applied.
Use of oversized capacitors and resistors for the zobel network to ensure reliable operation in PFFB mode.
Use of bulk capacitance in AVDD supply for improvement in sound quality.
Use of voltage supervisor IC to avoid large turn on-off pops or clicks.
Difference with Sylph-D400M is that this module uses a single rail supply for the opamp buffer, ideal for those who already have an external buffer thqt connects directly to the chip. And for those who want to use this module for driving 2 ohms subwoofer.
