TDA1908 AUDIO AMPLIFIER
DESCRIPTIONThe TDA1908isa monolithic integrated circuitin lead quad in-line plastic package intendedfor
low frequency power applications.The mountingis
compatible with the old types TBA800, TBA810S,
TCA830S and TCA940N.Its main features are: flexibilityin use witha max output curentof 3A
andan operating supply voltage rangeof 4Vto
30V; protection against chip overtemperature; soft limitingin saturation conditions; low ”switch-on” noise; low numberof external components; high supply voltage rejection; very low noise.
