SGS Thomson Microelectronics TDA1910 Datasheet
10W AUDIO AMPLIFIERWITHMUTING
DESCRIPTION
The TDA 1910 is a monolithicintegratedcircuit in
MULTIWATT package, intended for use in Hi-Fi
audiopowerapplications,as high quality TV sets.
The TDA 1910 meets the DIN 45500 (d = 0.5%)
guaranteed output power of 10W when used at
24V/4W.At 24V/8Wthe output power is 7W min.
Features:
– muting facility
– protection against chip overtemperature
– very low noise
– high supplyvoltage rejection
– low ”switch-on”noise.
The TDA 1910 is assembled in MULTIWATT
packagethat offers:
– easy assembly
– simple heatsink
