TDA1908
8W AUDIO AMPLIFIER
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
compatible with the old types TBA800, TBA810S,
TCA830S and TCA940N. Its main features are:
鈥?flexibility in use with a max output curent of 3A
and an operating supply voltage range of 4V to
30V;
鈥?protection against chip overtemperature;
鈥?soft limiting in saturation conditions;
鈥?low 鈥漵witch-on鈥?noise;
鈥?low number of external components;
鈥?high supply voltage rejection;
鈥?very low noise.
