EUA2318XIR1

DESCRIPTION

The EUA2318 is a high efficiency, 2 channel bridged-tied

load (BTL), class-D audio power amplifier. Operating from

a 16V power supply, EUA2318 is capable of delivering

15W/ channel of continuous output power to a 8Ω load

with 10% THD+N. The EUA2318 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 G0 and G1 gain select pins. Advanced

EMI suppression technology enables the use of

inexpensive ferrite bead at the outputs while meeting EMC

requirements.

The speaker protection circuitry is integrated into

EUA2318 to limit the amount of current through the

speaker. Meanwhile, the AGC detects output signal clip

due to the over level input signal and suppresses it

automatically. The EUA2318 also features short-circuit and

thermal protection preventing the device from being

damaged during a fault condition. The EUA2318 is

available in thermally efficient 28-pin TSSOP package.
