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 |
