General Description
The EL2176C EL2276C are single dual current-feedback oper-
ational amplifiers which achieve a b3 dB bandwidth of 70 MHz
at a gain of a1 while consuming only 1 mA of supply current
per amplifier They will operate with dual supplies ranging
from g1 5V to g6V or from single supplies ranging from a3V
to a12V The EL2176C EL2276C also include a disable power-
down feature which reduces current consumption to 0 mA while
placing the amplifier output in a high impedance state In spite
of its low supply current the EL2276C can output 55 mA while
swinging to g4V on g5V supplies The EL2176C can output
100 mA with similar output swings These attributes make the
EL2176C EL2276C excellent choices for low power and or low
voltage cable-driver HDSL or RGB applications
For Single Dual and Quad applications without disable consid-
er the EL2170C (8-Pin Single) EL2270C (8-Pin Dual) or
EL2470C (14-Pin Quad) For higher bandwidth applications
where low power is still a concern consider the EL2180C
El2186C family which also comes in similar Single Dual and
Quad configurations The EL2180C EL2186C family provides a
b3 dB bandwidth of 250 MHz while consuming 3 mA of supply
current per amplifier
