EUA2101A
10-W Stereo Class-D
Audio Power Amplifier
DESCRIPTION
The EUA2101A is a high efficiency, 2 channel bridged-tied
load (BTL), class-D audio power amplifier. Operating from
a 12V power supply, EUA2101A is capable of delivering
10W/ channel of continuous output power to a 8load
with 10% THD+N. The EUA2101A features a differential
input architecture offering improved noise immunity over a
single-ended (SE) input amplifier. Amplifier gain is
internally configured and can be selected to 20, 26, 32 or
36dB utilizing the Go and G1 gain select pins.
The EUA2101A also features short-circuit and thermal
protection preventing the device from being damaged
during a fault condition. The EUA2101A is available in
thermally efficient 48-pin TQFP package.
FEATURES
Wide Supply Voltage: 8V to 15V
Unique Modulation Scheme Reduces EMI Emission
10-W/ch into an 8-Load From a 12-V Supply
15-W/ch into an 4-Load From a 12-V Supply
