TDA1910 is a 10W audio amplifier integrated circuit with muting function, suitable for high-fidelity audio power applications, such as high-quality TV sets. It features low noise, high supply voltage rejection, low switch-on noise, etc.
The TDA1910 is a monolithic integrated circuit in a MULTIWATT® package, intended for high‑fidelity audio power applications such as TV sets. It provides a muting facility, over‑temperature protection, very low noise, and high supply‑voltage rejection.
Key specifications include a guaranteed 10 W output at 24 V/4 W, a maximum supply voltage of 30 V, output peak current up to 3.5 A (non‑repetitive), efficiency up to 62 % at 24 V, and a small‑signal bandwidth of 10 kHz to 120 kHz. The datasheet also contains mechanical dimensions, pin‑out diagrams, test circuits, and application examples with and without muting.
