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 8Ω load
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.

Application Information
Differential Input
The differential input stage of the amplifier cancels any common-mode noise that appears on both input lines of the audio
channel. To use the EUA2101A with a differential source, connect the positive signal of the audio source to the INP pin
and the negative signal from the audio source to the INN pin (Figure 30).
