E-TDA7375V Integrated Circuits (ICs)

The E-TDA7375V is a linear amplifier providing excellent audio performance within automotive head units and home theatre systems. Its capability to deliver high-quality sound with low distortion values, low power consumption and adjustable gain makes it a perfect choice for any application. This article examines the application field and working principle of the E-TDA7375V.

The E-TDA7375V is designed to provide an adjustable linear amplification of audio signals in accordance with the levels set by the consumer. It is particularly suitable for low-voltage applications, such as automotive head units, car stereos and home theatre systems. Adapted for automotive applications, the E-TDA7375V can operate with a supply voltage ranging from 4V to 15V with a maximum output power of 14W. It is highly reliable, as it is protected from output over-voltage, overcurrent and thermal protection.

The E-TDA7375V is a bipolar virtual ground amplifier with low-distortion, low-noise and low power consumption. It is based on a combination of the bipolar architecture and fully adjustable voltage divider, supporting a wide voltage range on the output. The automatic gain control (AGC) circuit incorporated into the device provides a wide range of output levels. The device requires an external gain setting resistance, which can be adjusted to set the output gain.

The E-TDA7375V amplifier outputs a high-current output signal, with good signal-to-noise ratio and low distortion level. The input signal is amplified through a three-stage differential amplifier stage followed by an adjustable voltage divider. This combination of components provides a highly accurate amplification with a wide bandwidth and a minimum signal-to-noise ratio. The output stage is composed of an emitter-follower, which provides an increased current capability compared to a traditional resistor-capacitor voltage divider.

The E-TDA7375V is a specifically designed linear amplifier providing excellent audio performance while consuming little power. It can be used in automotive head units, car stereos and home theatre systems, offering high-quality sound with low power consumption, low distortion values and adjustable gain. The device consists of a three-stage differential amplifier followed by a voltage divider for increased current capability, providing a wide range of output levels. Overall, the E-TDA7375V is a great solution for any audio application.
