EUA2100
20-W Stereo Class-D
Audio Power Amplifier
DESCRIPTION
The EUA2100 is a high efficiency, 2 channel bridged-tied
load (BTL), class-D audio power amplifier. Operating from
a 18V power supply, EUA2100 is capable of delivering
20W/ channel of continuous output power to a 8Ω load
with 10% THD+N. The EUA2100 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 EUA2100 also features short-circuit and thermal
protection preventing the device from being damaged
during a fault condition. The EUA2100 is available in
thermally efficient 48-pin TQFP package.
