Using this method, very high efficiency is achieved. The principle of operating with two supply voltages (class G) makes it possible to fix the supply voltage ‘ : : Vp optimum for the scan voltage and the second supply Pin Configuration sche Vep optimum for the flyback voltage. The flyback voltage is determined by an additional supply voltage Veg. In the application it is recommended that Vgiff = 1.5 V (typ), This is recommended because of the spread of input current and the spread in the value of RCON The maximum input differential voltage is }. The output current is adjustable from 0.5 A (p-p) to 3 A (p-py by varying RM. The relationship between the differential input current and the output current is defined by: An external resistor (RCON) connected between the differential input determines the output current through the deflection coil. The input circuit has been adapted to enable it to be used with the TDA9150A, TDA9151B, TDA9160A, TDA9162, TDA8366 and TDA8376 which deliver symmetrical current signals. ![]() The analog multi-channel sound systems (A2, A2+ and AP) are sometimes also named 2CS (2 carrier systems).ĭriven. It is based on M standard.Īn overview of the supported standards and sound systems and their key parameters is given in.(Table 1). Differences include deviation, modulation contents and identification. Korea has a stereo sound system similar to Europe and is supported by the TDA9870A. M standard is transmitted in Europe by the American Forces Network (AFN) with European channel spacing (7 MHz VHF, 8 MHz UHF) and monaural sound. In other application areas there exists only subsets of those standard combinations otherwise only single standards. This includes B/G, D/K, |, M and L standard. The multistandard/multi-stereo capability of the TDA9870A is mainly of interest in Europe, but also in Hong Kong/Peoples Republic of China and South East Asia. ![]() #Tevion music audio converter tv#The TDA9870A is a single-chip Digital TV Sound Processor (DTVSP) for analog multi-channe! sound systems in TV sets and satellite receivers.
