General Description
The EL2176C EL2276C are single dual current-feedback oper-
ational amplifiers which achieve a
b
3 dB bandwidth of 70 MHz
at a gain of
a
1 while consuming only 1 mA of supply current
per amplifier They will operate with dual supplies ranging
from
g
1 5V to
g
6V or from single supplies ranging from
a
3V
to
a
12V 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
g
4V on
g
5V 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
b
3 dB bandwidth of 250 MHz while consuming 3 mA of supply
current per amplifier
