TDA1905
5W AUDIO AMPLIFIER WITH MUTING
DESCRIPTION
The TDA1905 is a monolithic integrated circuit in
POWERDIP package, intended for use as low
frequency power amplifier in a wide range of appli-
cations in radio and TV sets:
– muting facility
– protection against chip over temperature
– very low noise
– high supply voltage rejection
– low ”switch-on” noise
– voltage range 4V to 30V
The TDA 1905 is assembled in a new plastic pack-
age, the POWERDIP, that offers the same assembly
ease, space and cost saving of a normal dual in-line
packagebut with a power dissipationof up to6W and
a thermal resistance of 15°C/W (junction to pins).
