TDA1908
DESCRIPTION
The TDA1908 is a monolithic integrated circuit in 12 lead quad in-line plastic package intended for low frequency power applications. The mounting is patible with the old types TBA800, TBA810S, TCA830S and TCA940N. Its main features are:
- flexibility in use with a max output curent of 3A and an operating supply voltage range of 4V to 30V;
- protection against chip overtemperature;
- soft limiting in saturation conditions;
- low ”switch-on” noise;
- low number of external ponents;
- high supply voltage rejection;
- very low noise. ABSOLUTE MAXIMUM RATINGS
