You can modify most readymade amplifier kit to LA4440 bridge amplifier circuit by simply cutting some PCB tracks and adding some jumpers, but that may vary board to board. TDA 2050 is a monolithic integrated circuit in Pentawatt package, intended for use as an audio class AB audio amplifier. 0. Differential Amplifier as Comparator. When the IC LA4440 is in Bridge mode in the circuit, its output power is 19w. Also, it requires very few components which are very cheap and easy to obtain. A differential amplifier circuit is a very useful op-amp circuit, since it can be configured to either “add” or “subtract” the input voltages, by suitably adding more resistors in parallel with the input resistors. Wheatstone Bridge INA. Here is simple circuit of bridge power audio amplifier used in application requiring more power than is provided by the single LM380 amplifier, the two LM380s can be used in the bridge configuration shown in figure 1. This amplifier has four pieces of power IC TDA7294. So it’s 19+19 stereo amplifier circuit diagram.
