Parallel mode is possible by connecting several devices and using pin11. High output power can be delivered to very low impedance loads, so optimizing the thermal dissipation of the system Table 1. Device summary Figure 1. TDA7293 block diagram Order code Package TDA7293V Multiwatt15V TDA7293HS Multiwatt15H Multiwatt15V Multiwatt15H IN- 2 R2. Short-circuit protected (with no input signal applied) Thermal shutdown Clip detector Modularity (several devices can easily be connected in parallel to drive very low impedances) Description The TDA7293 is a monolithic integrated circuit in Multiwatt15 package, intended for use as audio class AB amplifier in Hi-Fi field applications, such.
As part of my home theater build, have decided to go for 3 way actives for front LCR… so, need to build 9 power amps for fronts and 8 amps for surrounds… to pair up with my Sherbourn PT-7020A pre/pro.
I needed something as easy, but more powerful. This is when I and my friend John found the datasheet of TDA7293. This IC can run up to 100V, low distortion, and can easily be paralleled. Having built single chip amp and extensive listening TDA7293 is my favorites for IC power amp applications.
I have been looking for a source of PCBs using parallel TDA7293s… there are not many out there that you can buy. We then decided to do our own PCB. Our schematic is almost the same as in datasheet.. the board layouts in the datasheet are flawed and little clumsy… we used them only as guidance with component arrangement on our PCB after few futile attempts to route the board with minimum jumper count. Pin out on TDA7293 is tricky, so single-sided board is difficult to draw, and in the end contains more jumpers between lines than tracks… so, this one is made as double sided.
I thought it would be good to share my project with the community… maybe someone finds it useful. Tentative double side PCB layout, top and bottom sides… have to check pitch and spacing with actual components we have before fabricating the PCB.
Between each revision, John will suggest this and suggest that, to improve the schematic and layout. Revised and final:
The TDA7293 amp belongs to a sort of class-AB audio power amplifiers, which is a monolithic integrated circuit available in Multiwatt15 package, 120 V / 100 W DMOS audio amplifier with mute and standby. The TDA7293 is designed for use as audio class AB amplifier in Hi-Fi field applications, such as home stereo, self powered loudspeakers and Topclass TV. Owing to the wide voltage range and to the high output current capability, TDA7293 amplifier is able to supply the highest power into both 4-Ω and 8-Ω loads. The built-in muting function with turn-on delay simplifies the remote operation avoiding on-off switching noises. Parallel mode is possible by connecting several devices and using pin11. High output power can be delivered to very low impedance loads, so optimizing the thermal dissipation of the system.
