EUA4996

EUA4996 2.8-W Stereo Fully Differential Audio Power Amplifier DESCRIPTION The EUA4996 is a stereo fully-differential audio amplifier, capable of delivering 2.8W/channel of continuous output power to a 3Ω load with 10% THD+N from a 5V power supply. The EUA4996 features independent shutdown control for each channel. The feedback resistors are internal, allowing the gain to be set with only two input resistors per channel. High PSRR and fully differential architecture provide increased immunity to noise and RF rectification, and a fast startup time with minimal pop, making the EUA4996 idea for notebook PC, smart phone applications. FEATURES z Output Power - 2.8W/Ch Into 3Ω at 5V, THD=10% (Typ.) - 1.99W/Ch Into 4Ω at 5V, THD=1% (Typ.) - 1.27W/Ch Into 8Ω at 5V, THD=1% (Typ.) Wide Supply Voltage: 2.5V to 5.5V Independent Shutdown Control for Each Channel High PSRR : 86dB Fast 23ms Startup Time with Minimal POP Low 8mA Quiescent Current at 5V Supply and 1µA Shutdown Current Thermal Protection 4mm × 4mm TQFN-16 Package RoHS Compliant and 100% Lead(Pb)-Free z z z z z z z z APPLICATIONS z Notebook PCs z Smart Phones Typical Application Circuit VÛm w`R yÑb € ww w.g ofot ech. com Figure 1.
