TDA3009
Edition 09/00
25 W + 25 W Stereo Amplifier
Short Description
Features
The integrated circuits TDA3009 S and TDA3009 M are
dual audio power amplifiers for high quality audio
equipment such as Hi - Fi - Stereo - amplifiers, TV
amplifiers and high power bridge amplifiers.
The TDA3009 M is specially designed for bridge mode
applications.
• High output power
( typ. 25 W each channel @ THD = 10 % )
• High output current capability ( up to 4.5 A )
• AC short circuit protection
• Thermal overload protection
• SOAR protection
• Few external components
• Reduced switch-on / switch-off clicks
• Stand - by option
Package
• TO 220 / 11

Application Hints
• The IC TDA3009 requires a weel-filtered supply voltage, the recommended voltage range for safe operation
is 8 ... 32 V.
• To avoid the danger of oscillations the supply voltage must be filtered by means of an electrolytic capacitor
≥ 1000 µF as near possible at the pin nine.
• The capacitor at pin 3 ( ≥ 10 µF ) permits to increase the supply voltage ripple rejection ( SVR ), recommended
value of this capacitor for good SVR is 100 µF.
• Via pin three the IC TDA3009 can be switched into standby mode, when the pin three is connected to ground
or a voltage less than 0.7 V. In standby mode the current consumption decreases down to ≈ 4 mA.
• For a good frequency stability between output pins (eight and ten) and ground Boucherot cells should be
connected. The values of these elements are recommended with R = 1 ... 2.7 Ω and C = 100 ... 220 nF.
• Input ground and output ground areas must be separately connected to pin six.
• The ground points of the feedback network (for voltage gain determination) must be connected to input ground.
