Integrated OCL power amplifier circuit composed by the TDA2040


Posted on Mar 28, 2007

By an integrated power amplifier TDA2040 (lC) can also form OCL power amplifier (OCL meaning is no output capacitor power amplifier). Circuit shown in Figure 10-10, which uses

symmetrical 1V dual supply as operating voltage. 0CL amplifier thanks to said positive and negative power supply, so do not need to input bias circuit. The voltage gain of the circuit is determined by the code and Rz, magnification A R3/R2. Cj and C5, C6 and C7 are positive and negative power supply filter capacitor.
