Tda7379 amplifier circuit

Types of TDA7379 Amplifier Circuits

A TDA7379 amplifier circuit is an integrated car radio amplifier chip that makes a stereo from a speaker. The kind of tda7379 amplifier circuit varies according to number of channels they amplifies signals to.

• Two-channel amplifier circuit: This kind of amplifier takes the weak signals from the radio and boosts them to drive two speakers in one possible configuration of a sound system.
• Multi-channel amplifier circuit: Some more advanced sound systems require many speakers for total surround sound. Such systems use four-channel or six-channel amplifiers that take weak signals from the radio and boost them to drive four or six speakers, respectively.

Functions and Features

• Compact and Cost-Effective Design:

  This circuit offers a compact solution for medium-sized audio amplification systems that are both space-efficient and financially accessible. Its small size makes it easy to integrate into various devices without taking up too much space. Additionally, being cost-effective makes it an affordable option for those looking to enhance their device's audio capacity without incurring high expenses.

• Built-in Output Protection Circuit:

  The presence of an output protection circuit is vital as it safeguards both the amplifier and the speakers from potential harms such as DC leaks or damaging high-voltage pulses. These issues, if unchecked, could severely affect the equipment's longevity and functionality. Thus, an integrated protection circuit enhances the reliability and durability of the amplifier while ensuring connected speakers remain unharmed.

• Volume Control Potentiometer:

  A volume control potentiometer is crucial as it offers a straightforward method to adjust the audio output level according to individual preferences. Placed directly in the signal path, it efficiently manages the amplified signal's level, ensuring one can raise or reduce the volume depending on the desired listening level. Its direct integration into the signal path underlines its effectiveness in controlling audio levels.

• Power Supply and Ground Connections:

  The power supply and ground connections are fundamental requirements for any electronic circuit to function. They provide the necessary power for the circuit's operation and serve as a common ground reference for all components, ensuring proper electrical balance and minimizing noise or interference issues. Without these connections, the circuit cannot operate or maintain stable electrical conditions.

• PCB Mounting Options:

  PCB mounting options, such as through-hole and surface mount, are essential for securely attaching components to the printed circuit board. Through-hole mounting involves components with leads that pass through the board and are soldered on the opposite side, providing strong mechanical connections ideal for components that need to be repeatedly connected and disconnected. On the other hand, surface mount technology has components soldered directly onto the board's surface, suitable for parts mounted directly onto the circuit board. This method is commonly used for components like resistors, capacitors, and ICs, allowing for compact assembly of miniaturized surface mount components. Both through-hole and surface mount options are crucial for reliably mounting electronic parts onto PCBs, ensuring circuits operate as intended.

How to choose TDA7379 amplifier circuits

Wholesale buyers carefully consider what their customers need before buying. That is why they look at market trends and buy car radio amplifier circuits that are in demand. They also buy amplifier circuits that are compatible with current products. When buying TDA7379 circuits, buyers should look for:

• Protection Circuits

  Complete protection circuits can prevent damage to the amplifier and speakers from high voltage, short circuits, and overheat. The Circuit can also prevent low voltage operation. The Circuit will disconnect the power supply when it detects any of these dangerous situations. Also, the circuit will stop the system from working until it is safe to operate once more. There is no need for manual intervention to reconnect power when protection circuits disconnect the system.

• Amp Output and Channels are Suitable for Customers' Applications

  The output power of the amplifier circuit should be able to drive the speakers' load without distortion. While many customers will be happy with a circuit that has 4 x 20W output power, others may prefer 4 x 35W or higher. Buyers who order 4 OHM and 8 OHM speaker compatibility circuits will meet the needs of various customers. Some buyers order circuits with different output power and impedance compatibility to satisfy different customer amplifier requirements.

• Coolers for Circuits that have higher Output Power

  Amplifier circuits with higher output power require better cooling or larger heat sinks. Circuits that operate at higher power levels are more likely to get hot. Buyers whose customers use circuits in hot climates or for long periods of time should buy amplifier circuits with larger heat sinks.

• Power Supply Voltage that Matches Customers' Applications

  Most car radio amplifier circuits use a power supply with a voltage from 12V to 14.4V. However, some circuits designed with TDA7379 can operate with higher power supply voltages. Circuits with high voltage capacity use more components that can stand high voltage. These circuits will satisfy customers who use amplifiers in areas where the power supply voltage exceeds 14.4 volts. They will also offer more options to customers whose devices are compatible with higher power supply voltages.
