![]() ![]() If you want to build this project a PCB layout as well as TDA7293 BOM are provided for free, as is, no warranty. The slave power output stages are driven by the master device and will work in parallel together, while the input and the gain stages of the slave devices are disabled. In this type of application one TDA7293 device will operate as the master and the rest of TDA7293 will function as slaves. Using the modular application of TDA7293 produces very high power output to a very low-Ζ load. ![]() This project is the modular application of several TDA7293 devices that operates in parallel. ![]() Modularity (several devices can easily be connected in parallel to drive very low impedances). ![]() Short-circuit protected (with no input signal applied).High output power (100 W into 8 Ω THD =10%, with V S= ±40 V).Very high operating voltage range (±50 V).More information is available at ST Microelectronics website. The device is using the BCD technology a mixed bipolar and power MOS devices. The TDA7293 is a monolithic integrated circuit in Multiwatt15 package, intended for use as audio class AB amplifier in high fidelity applications. ![]()
