NAU82039 – New High Efficiency Device Ideal for Smart Phones, Tablets, Docking Stations, Portable Media Players, LCD/LED TV, Toys
Nuvoton Technology Corporation introduced the NAU82039, a family of new Class-D audio amplifiers designed to optimize portable consumer devices. The new Nuvoton NAU82039 features high-efficiency mono, analog-input 3.2W Class-D power amplifier with 12dB of fixed gain – ideal for mobile consumer electronics such as smart phones, tablet PC, docking stations, portable audio and video players, GPS/Navigators, LCD and LED TVs, and toys.
The NAU82039 mono Class-D audio amplifier sets a new standard in audio amplifiers by offering an ultra-low quiescent current (1.25mA at 3.6V) for output power delivered, allowing the device unparalleled for the portable applications where battery life represents a significant differentiating factor. This new amplifier’s inputs can be configured in either single-ended or differential mode.
Superior EMI Performance, Filter-free
The NAU82039 amplifier does not need an external output filter, as each reduces electromagnetic interference (EMI) through spread-spectrum-oscillator technology and slew-rate control. Moreover, the NAU82039 provides improved immunity and power supply rejection ratio, or PSRR, of > 90dB at 217Hz, making the devices ideal Class-D audio amplifiers for wireless and AM frequency band applications.
The Class D NAU82039 is capable of driving a 4Ω load with up to 3.2W output power, and features a chip-enable pin for extremely low standby current and fast start-up time of 4ms.
Availability, Pricing
The NAU82039 is available now in Miniature WLCSP-9 (1.21mm × 1.23mm in 0.4mm pitch) package and priced at $0.20.
