UTCTEA2025A LINEAR INTEGRATED CIRCUIT

2.3W DUAL AUDIO POWER

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=4Ω

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
