TEA2025A
LINEAR INTEGRATED CIRCUIT
STEREO AUDIO AMPLIFIER
DESCRIPTION
The UTC TEA2025A is a monolithic integrated circuit, consisting of a 2-channel power amplifier.
It is suitable for stereo and bridge amplifier application of radio cassette tape recorders.
FEATURES
* High output power Stereo: Po=2.
3W (Typ) at Vcc=9V, RL=4 Ω Bridge: Po=4.
7W (Typ) at Vcc=9V, RL=8Ω
* Low switching distortion at high frequency * Small shock noise at the time of power on/off dur to a built-in
muting circuit * Good ripple rejection due to a built-in ripple filter * Good channel separation * Soft tone at the time of output straiten * Closed loop
voltage gain fixed 45dB (B...
