EUA2107
6.5-W Mono Class-D
Audio Power Amplifier
DESCRIPTION
The EUA2107 is a high efficiency, mono bridged-tied load
(BTL), class-D audio power amplifier. Operating from a
12V power supply, EUA2107 is capable of delivering
6.5W of continuous output power to a 8Ω load with 10%
THD+N. The EUA2107 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 12, 18, 23.6 or
35.5dB utilizing the Go and G1 gain select pins.
The EUA2107 also features short-circuit and thermal
protection preventing the device from being damaged
during a fault condition. The EUA2107 is available in
thermally efficient 24-pin TSSOP package and does not
require an external heat sink.
