SGS-THOMSON TDA1905 Audio Amplifier Datasheet
The TDA1905 is a monolithic audio power amplifier IC supplied in a POWERDIP package. It offers a muting facility, over‑temperature protection, very low noise, high supply‑voltage rejection and low switch‑on noise. The device operates from 4 V to 30 V and can dissipate up to 6 W.
Key specifications include a non‑repetitive output peak current of 3 A, repetitive current of 2.5 A, thermal resistance of 15 °C/W (junction‑to‑pins), and a typical voltage gain of 75 dB (open‑loop). The datasheet also contains pin‑out diagrams, test circuits, mechanical dimensions and application examples with and without muting.
