EL2176C/EL2276C
70 MHz/1 mA Current Mode Feedback Amp w/Disable
Features
# Single (EL2176C) and dual
(EL2276C) topologies
General Description
The EL2176C/EL2276C are single/dual current-feedback oper-
b
ational amplifiers which achieve a 3 dB bandwidth of 70 MHz
at a gain of 1 while consuming only 1 mA of supply current

# 1 mA supply current (per

per amplifier. They will operate with dual supplies ranging
a
from 1.5V to 6V, or from single supplies ranging from 3V
to 12V. The EL2176C/EL2276C also include a disable/power-

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 4V on 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
# Large output drive current:
100 mA (EL2176C)
