TEA2025A

UNISONIC TECHNOLOGIES CO.,LTD. TEA2025A LINEAR INTEGRATED CIRCUIT STEREO AUDIO 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=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  ORDERING INFORMATION Order Number TEA2025AG-D12-H-T Package DIP-12H Packing Tube  MARKING www.unisonic.com.tw Copyright © 2014 Unisonic Technologies Co.,Ltd. 1 of 8 QW-R107-012.C TEA2025A  PIN CONFIGURATION BTL OUT OUT 2 B.S.2 1 2 3 LINEAR INTEGRATED CIRCUIT 12 VCC 11 OUT 1 10 B.S.1  BLOCK DIAGRAM NF2 4 IN 2 5 DC 6 9 NF1 8 IN 1 7 PRE GND UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 8 QW-R107-012.C TEA2025A LINEAR INTEGRATED CIRCUIT  ABSOLUTE MAXIMUM RATINGS (TA=25°C, unless otherwise specified) PARAMETER SYMBOL RATINGS UNIT Supply Voltage Power Dissipation VS 15 V PD 4 W Operating Temperature Storage Temperature TOP...
