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:
– 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 components;
– high supply voltage rejection;
– very low noise.
