TDA7293 is a monolithic integrated circuit package for Multiwatt15, audio and video AB amplifier for high fidelity applications. TDA7293 operating voltage range (±50V) maximum operating voltage ±60V DMOS power stage high product power (100W @ THD = 10%, RL = 8 ohms = ±40V) The audio amplifier circuit diagram is as follows: The PCB is as follows:
Broadband filter is a kind of passband filter. A filter used to separate a wide band monochromatic light from composite light. Half width of passband Δλ ≥0.01 λ 0, where λ 0 is the central wavelength of the light transmission curve of the filter. If the central wavelength of the filter is 500 nm, the half width of the passband of the filter is ≥ 5 nm.
