Sylph-D100 TPA3255 Mono/Stereo Amplifier Module (Ready to Run)

$132.00 USD Coming Soon

Mid-power chip-based class-D amplifier with sound improvements through optimization and careful parts selection.

The analog input can accept full balanced or single ended signals which can be configured by a solder jumper under the PCB. Single ended input is enabled by default unless otherwise requested.

A split supply is used in the opamp buffer section in order to delete the redundant input coupling caps in the frontend audio path. The opamp rail supplies are being generated on-board with positive and negative post regulators. Each opamp has a separate bulk capacitance on its positive and negative rails.

Use of bulk capacitance in AVDD supply, and various tweaks to improve the sound quality.

Use of voltage supervisor IC to avoid large turn on-off pops or clicks.

Input coupling caps layout can accomodate to 7.5mm x 7.5mm, 5mm pitch poly caps.

Can be configured as a mono PBTL on post LC filter (select mono PBTL on checkout).
