TDA1910
10W AUDIO AMPLIFIER WITH MUTING
10W AUDIO AMPLIFIER WITH MUTING
DESCRIPTIONThe 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
