TEA2025A
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.
Key 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 (Bridge: 51dB) but availability with external resistor added * Minimum number of external parts required * Easy to design radiator fin
