eua2110 功放ic

description
the eua2110 is a high efficiency, 2 channel bridged-tied
load (btl), class-d audio power amplifier. operating from
a 16v power supply, eua2110 is capable of delivering
15w/ channel of continuous output power to a 8ω load
with 10% thd+n. the eua2110 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. 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
eua2110 to limit the amount of current through the
speaker. the eua2110 also features short-circuit and
thermal protection preventing the device from being
damaged during a fault condition. the eua2110 is
available in thermally efficient 28-pin tssop package.
