NAU82110YG – The New High-E Audio Device Ideal for Bluetooth Speakers, Wireless Doorbells, Outdoor Surveillance Systems, and Handheld Game Consoles
Nuvoton announced the NAU82110YG, a new Class-D audio amplifier. The NAU82110YG Class-D amplifier features high-efficiency mono, analog input, and delivers up to 10W (8 Ω load) or 18W (4 Ω load) output power. With multiple gain adjustment options, it is the ideal choice for consumer electronics applications such as Bluetooth speakers, wireless doorbells, outdoor surveillance systems, and handheld gaming consoles.
As the importance of quality of life grows, music plays an increasingly vital role in daily lives, driving strong demands for superior sound. Consumers now seek high-quality audio and advanced products, making power efficiency and noise reduction crucial in the electronics market. To address these needs, Nuvoton has introduced the NAU82110YG, a next-generation Class-D amplifier. This innovative product offers lower power consumption, reduced noise, and a range of features designed to enhance user experience.
The NAU82110YG mono Class-D audio amplifier features low quiescent current (6 mA @ 12V), high output power, and comprehensive device protection, suitable for various consumer audio applications. Additionally, this new amplifier supports both single-ended and differential input signal modes, providing flexibility for audio setup.
NAU82110YG Key Features
- Multiple Gain Settings:
- Configurable via I2C interface with 32 gain levels
- Selectable via control pins with five preset gains: 0 dB / 20 dB / 24 dB / 32 dB / 36 dB
- Comprehensive Device Protection:
- Overcurrent Protection (OCP)
- Overvoltage Protection (OVP)
- Undervoltage Lockout (UVLO)
- Overtemperature Protection (OTP)
- Speaker Protection: Anti-Clipping Protection (ACP)
- Package: QFN20
- Operating Temperature Range: -40°C ~ 105°C
Superior EMI Performance, Filter-Free
The NAU82110YG amplifier stands out by eliminating the need for an external output filter, thanks to its spread-spectrum-oscillator technology and slew-rate control, effectively reducing electromagnetic interference (EMI). Moreover, it offers enhanced immunity and power supply rejection ratio (PSRR) of > 83 dB at 217 Hz. With an exceptional signal-to-noise ratio (SNR) of 103 dB, the NAU82110YG is an excellent fit for Class-D audio amplifiers in wireless and AM () frequency band applications.
Leap Forward in Efficiency and Power
The Class-D topology represents a significant leap forward in both power efficiency and noise minimization in audio devices. By generating a binary square wave, Class-D amplifiers efficiently amplify the signal through power device switching. Compared to Class-AB devices, Class-D amplifiers offer power efficiencies that are two-thirds better.
The NAU82110YG Class-D audio amplifier excels in driving a 4 Ω load with an impressive output power of up to 18W and features a chip-enable pin for a fast start-up time of just 4.6 ms.
NAU82110YG Target Applications
The new Class-D audio amplifier is designed for consumer electronics applications including Bluetooth speakers, wireless doorbells, outdoor surveillance systems, and handheld gaming consoles.
