The TDA7052B/N1,112 is a Linear – Amplifiers – Audio device. It is an 8-pin low power audio amplifier designed to provide quality audio power and performance. It is suitable for both low-impedance and high-impedance speakers and supports up to 40mW of power output at 8Ω.

The TDA7052B/N1,112 is capable of providing a maximum closed-loop voltage gain of 40dB. It can be powered by a simple dual supply of 3V to 14V and requires a very low quiescent current consumption of just 0.3mA. Additionally, it has a wide temperature range of -40°C to +85°C for reliable performance in harsh environments.

This TDA7052B/N1,112 device also features a built-in short-circuit protection and thermal shut down circuits to prevent any damage to the equipment in case of any fault condition. The thermal shut down is typically disabled and kept off at start-up, with the power dissipation automatically reducing and keeping the device within its normal operating temperature range.

The main application field of the TDA7052B/N1,112 is in consumer and automotive audio electronics, such as portable radios, TV, car audio, and clock radios etc. It is also suitable for use in other applications such as telephone voicemail applications and medical equipment.

The working principle of the TDA7052B/N1,112 is very simple. It consists of an NPN transistor and PNP transistor connected in a compound Darlington configuration, which allows it to achieve an output current of up to 4A. The amplifier has an N-channel input stage, which converts the input signal into an output voltage. This voltage is then amplified by the PNP transistor, which provides current gain and additional amplification. The transistor provides a negative feedback loop, which ensures that the gain is kept at a constant level, ensuring that the output signal is consistent and uninterrupted.

The TDA7052B/N1,112 is a high-performance and reliable audio amplifier, which provides excellent audio power and performance. Its low power consumption and wide operating temperature range makes it suitable for a variety of audio applications. The fact that it can be powered by a simple dual supply of 3V to 14V and requires a very low quiescent current consumption adds to its appeal. Its built-in protection and thermal shut down features make it a great choice for consumer and automotive audio electronics.
