TOSHIBA TA7252AP TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC TA7252AP 5.9 WW AUDIO POWER AMPLIFIER The TA7252AP is audio power amplifier for consumer applications. It is designed for high power, low distortion and low noise. Since the package is a 7 pin SIP (Single Inline Package), it greatly simplifies construction of a power amplifier both in design and assembly. It is suitable for car radio power amplifier.

Measures against oscillation The purpose of capacitor : Cg is to prevent oscillation. This capacitor needs to be small temperature coefficient. So ceramic capacitor is unsuitable. A voltage gain less than 40dB results occasionally in a plastic oscillation. 3. Precaution at print board design (1) GND line The GND pin is only one in this Ic. When there is some common impedance between the input side Pin@ (GND) GND and the output side GND, electrical characteristics as THD Vcc LINE degrade. 3 GND lines (input, output and Vcc sides) should be branched at J the pin@ as shown (Fig.3). INPUT LINE PUT LINE (2) It is recommended to refer the standard print board. (Fig.3) STANDARD P.C.B. 76 5 4 3 2 _ ORD GND (Vcc) 5 Ww Vec = .
