TDA7293MOD
The
TDA7293MOD is the High Powered version of the TDA7293.
In this Modular configuration, two TDA7293 are used,
one as the Master while the other as a Slave. In the
Slave unit, the voltage section is disconnected. The
Master TDA7293 then drives the Slave's power mosfets.
This is equivalent to doubling the power mosfets of
the Master. Due to this unique feature in the TDA7293,
TDA7293MOD is capable of much higher power output,
particularly into 4 Ω.

The
TDA7293mod is one channel and is supplied
Unassembled. Two kits are required
for stereo.
To
complete the amplifier, the following are
needed
1) a power supply consisting of a power transformer,
filter capacitors and a bridge rectifier
2) a heatsink for the power mosfets
3) a metal case and the necessary connectors
