The E-TDA7404D is a special purpose Audio IC which is designed for low power audio amplifier applications. This IC is capable of delivering 4W of peak output power to an 8 ohm speaker in mono mode and 2W of peak power in both stereo mode and bridge mode. The headroom of the circuit is also relatively high compared to other ICs, which means even at low volumes, the sound will still be very clear and crisp.

The E-TDA7404D comes with a variety of features that make it ideal for portable audio applications such as home theaters, stereo systems, portable speakers and more. The device is simple to construct, requires few external components and is highly reliable.

It is based on a two-stage transistor architecture which consists of a pre-amplifier stage and power booster stage. The pre-amplifier stage consists of two differential inputs along with a dual control input. This allows the IC to accept both left and right audio inputs. The power booster stage consists of two push-pull/ Darlington transistors that are designed to provide high levels of output current. The internal design of the E-TDA7404D also allows for low harmonic distortion and a wide frequency range, making it suitable for the reproducing of a variety of audio formats.

The E-TDA7404D is a highly valuable Audio IC for low power audio amplifier applications. The two-stage transistor architecture and differential input provide excellent audio quality and low harmonic distortion. The output power is also sufficient for most portable audio applications, while the low power dissipation ensures that the E-TDA7404D is highly efficient. The wide frequency range also allows for the reproduction of a variety of audio formats. The E-TDA7404D is an ideal choice for applications in home theater systems, stereo systems and portable speakers.
