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 (Bridge: 51dB) but availability with external resistor added

* Minimum number of external parts required

* Easy to design radiator fin
