DescriptionThe TDA7050 is a low voltage audio amplifier for small radios with headphones (such as watch, pen and pocket radios)
in mono (bridge-tied load) or stereo applications.
The TDA7050 is designed as one kind of low voltage audio amplifier for small radios with headphones (such as watch, pen and pocket radios) in mono (bridge-tied load) or stereo applications.
Features of the TDA7050 are:(1)limited to battery supply application only (typ. 3 and 4 V);(2)operates with supply voltage down to 1,6 V;(3)no external components required;(4)very low quiescent current;(5)fixed integrated gain of 26 dB, floating differential input;(6)flexibility in use-mono BTL as well as stereo;(7)small dimension of encapsulation (see package design example).
The absolute maximum ratings of the TDA7050 can be summarized as:(1)supply voltage:max.6 V;(2)peak output current:max.150 mA;(3)total power dissipation:see derating curve fig.1;(4)storage temperature range:-55 to +150 °C;(5)crystal temperature:max.100 °C;(6)A.C. and d.c. short-circuit duration at VP=3,0 V (during mishandling):max.5 s.If you want to know more information such as the electrical characteristics about the TDA7050,please download the datasheet in www.seekic.com or www.chinaicmart.com .
