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 3load 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.
