Linear - Amplifiers - Audio: NAU82011WG TR application field and working principle

The NAU82011WG TR amplifier is a wide-supply, low-noise, H-bridge, audio amplifier. It is a high-performance, mono-channel amplifier specifically designed for driving both loudspeakers and headphones. The amplifier is designed for single-ended and differential output designs, offering wide bandwidth and high efficiency for driving audio streams with low to moderate power consumption. The NAU82011WG TR amplifier also provides a high-fidelity output for a wide range of applications.

The key feature of the NAU82011WG TR amplifier is its wide supply range. It is designed to operate from a wide voltage range of 4.5 to 28 volts. This wide supply range allows the amplifier to accommodate both the lower AC line voltage of mobile and laptop devices, as well as the higher power supply voltages of bigger audio systems. The supply voltage flexibility also makes the amplifier capable of driving both small and large speakers. Additionally, the amplifier has very low power consumption, which allows it to be used in battery-powered systems as well.

The NAU82011WG TR also offers excellent performance in terms of sound fidelity. It features low-noise operation and very low distortion figures (THD+N and IMD). The combination of these features makes it suitable for use in applications requiring wide dynamic range, high-fidelity and low-distortion audio. Additionally, the amplifier is designed with a low source impedance for driving heavy loads, allowing it to achieve high efficiency with small to medium speakers. The power supply rejection ratio of 90dB and the high current sinking capability make this amplifier suitable for driving a wide variety of loads.

The NAU82011WG TR amplifier is designed to operate in both single-ended and differential output modes. In single-ended mode, the amplifier produces a single output voltage. In differential mode, the amplifier produces two output voltages that are 180° out-of-phase with each other. Using differential output mode allows the amplifier to reduce the amount of common-mode noise that might affect the audio signal, improving the overall sound quality of the system.

Aside from its excellent audio performance, the NAU82011WG TR is also extremely easy to use. It features a power-on reset circuit and a starting fault protection circuit that protects the amplifier from damage due to overload or out-of-range operating conditions. The amplifier also features an error flag circuit that allows the easy monitoring of its operation and detection of any faults. Additionally, the amplifier supports several safety and EMC regulations, making it suitable for use in many different applications.

In conclusion, the NAU82011WG TR amplifier is a great choice for applications requiring both wide bandwidth and high audio fidelity. Thanks to its wide supply range, low noise operation and high performance, it is suitable for driving both small and large speakers, allowing it to be used in a wide variety of applications. Additionally, its ease of use makes it a great tool for audio engineers looking for a reliable and powerful amplifier.
