EUA2061-3.2W Mono Class-D Audio Power Amplifier

EUA2061-3.2W Mono Class-D Audio Power Amplifier with Non-Clip and Power Limit DataSheet

DESCRIPTION
The EUA2061 is a high efficiency, 3.2W mono class-D
audio power amplifier with Non-Clip and Power Limit. A
low noise, filterless PWM architecture eliminates the
output filter, reducing external component count, system
cost, and simplifying design.
EUA2061 having power limit interlock non-clip function,
controls gain automatically and prevents output signals
from being clipped at the supply voltage. In addition, this
power limit function permits the maximum output to be
arbitrarily specified to 100mW to 1000mW according to a
speaker to use.
Furthermore, EUA2061 also integrate overcurrent and
overtemperature protection functions, DC output protection
function, under-voltage malfunction prevention function,
as well as EMI noise and the pop noise reduction
functions.
The EUA2061 is available in TDFN-8 and SOP-8
packages.
