TDA1521 or TDA2616 Dual channel OTL Power Amplifier

TDA1521 TDA2616 Dual channel OTL Power Amplifier

TDA1521 or TDA2616 Dual channel Power Amplifier Dual-channel HIFI Power Amplifier This is a pure final stage HIFI power amplifier based on TDA1521/TDA2616, which can be interchangeable, only with different pin connections for pin 2. TDA2616, compared to the well-known TDA1521, has added output short-circuit protection and supports 4-ohm speakers.

It is recommended to pair it with high-quality speakers of 3–4 inches, suitable for desktop or bookshelf speakers, with excellent results! To meet different needs, we specially provide two types of PCB, circular board and rectangular board, and optimize the grounding method. The listening effect is exceptional! Special reminder: when using the TDA2616 chip, pin 2 should be left floating; when using the TDA1521, pin 2 should be connected to pin 3! You can adjust the connection between pins 2 and 3 according to your chip and then sample the PCB.
