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.

FEATURES

* High output power

Stereo: Po=2.3 W (Typ.) at V CC =9.0V, R L =4.0Ω

Bridge: Po=4.7 W (Typ.) at V CC =9.0V, R L =8.0Ω

* 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
