The New Excessive-Effectivity Audio Resolution Splendid for Dashboard, eCall, and T-Field Purposes
Nuvoton introduced NAU83U25YG, a brand new automotive-grade Class-D audio amplifier. The NAU83U25YG Class-D amplifier options high-efficiency stereo, digital enter, and delivers as much as 3W (4 Ω load) or 1.7W (8 Ω load) output energy. That includes a two-wire acquire adjustment interface, it’s the superb selection for automotive electronics functions akin to dashboards, eCall, and T-Field techniques.
As automotive electronics enter the period of the “good cockpit,” car intelligence has change into a key business focus. This development is driving rising practical necessities for audio answer suppliers in automotive functions. Nuvoton Know-how strictly adheres to automotive business requirements, providing AEC-Q100 certified merchandise for automotive functions. To simplify system design, our options assist digital I2S audio sign enter from the car’s primary controller, decreasing the necessity for exterior parts and minimizing PCB dimension. Moreover, our digital amplifiers assist stop circuit interference and successfully clear up EMI points.
The NAU83U25YG stereo Class-D audio amplifier has superior options like 80 dB PSRR, 90% effectivity, ultra-low quiescent present (i.e. 2.1 mA at 3.7V for two channels) and superior EMI efficiency. It presents decrease distortion, diminished background noise, and a wider dynamic vary. Moreover, this new amplifier helps complete gadget safety.
NAU83U25YG Key Options
- Achieve Setting through I²C interface, 22 dB to -62 dB
- Highly effective Stereo Class-D Amplifier, 2ch x 3.0W (4Ω @ 5V, 10% THD+N)
- Low Output Noise: 18 μVrms @ 0 dB acquire
- Complete System Safety:
- Overcurrent Safety (OCP)
- Undervoltage Lockout (UVLO)
- Overtemperature Safety (OTP)
- Clock Termination Safety (CTP)
- Click on-and-Pop Suppression
- Bundle: QFN-20
- Working Temperature Vary: -40℃ ~ +105℃
- Automotive Grade: AEC-Q100 qualification & TS16949 compliant
Superior EMI Efficiency, Filter-Free
The NAU83U25YG amplifier stands out by eliminating the necessity for an exterior output filter, due to its spread-spectrum-oscillator know-how and slew-rate management, successfully decreasing electromagnetic interference (EMI). Furthermore, it presents enhanced immunity and energy provide rejection ratio (PSRR) of > 80 dB at 217 Hz. Making the NAU83U25YG a superb match for Class-D audio amplifiers in wi-fi and AM (Amplitude Modulation) frequency band functions.
Leap Ahead in Effectivity, Energy
The Class-D topology represents a big leap ahead in each energy effectivity and noise minimization in audio gadgets. By producing a binary sq. wave, Class-D amplifiers effectively amplify the sign by way of energy gadget switching. In comparison with Class-AB gadgets, Class-D amplifiers supply energy efficiencies which are two-thirds higher.
The NAU83U25YG Class-D audio amplifier excels in driving a 4 Ω load with a powerful output energy of as much as 3W and quick start-up time of simply 14 msec.
NAU83U25YG Goal Purposes
The brand new Class-D audio amplifier is designed for automotive electronics functions together with dashboards, eCall, ADAS (Superior Driver Help Methods) and T-Field.
