EUA4996

2.8-W Stereo Fully Differential

Audio Power Amplifier

DESCRIPTION

FEATURES

Output Power

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.

- 2.8W/Ch Into 3ꢀ at 5V, THD=10% (Typ.)

- 1.99W/Ch Into 4ꢀ at 5V, THD=1% (Typ.)

- 1.27W/Ch Into 8ꢀ 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
