DESCRIPTION
The TDA 1910 is a monolithic integrated circuit in
MULTIWATT® package, intended for use in Hi-Fi
audio power applications, 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/8W the output power is 7W min.
Features:
– muting facility
– protection against chip over temperature
– very low noise
– high supply voltage rejection
– low "switch-on" noise.
The TDA 1910 is assembled in MULTIWATT®
package that offers:
– easy assembly
– simple heatsink
Multiwatt 11V
ORDERING NUMBERS:
TDA1910 (Multiwatt11 Vertical)
TDA1910HS (Multiwatt11 Horizontal)
