EL2186C, EL2286C
250MHz/3mA Current Mode Feedback Amp w/Disable
Features
• Single (EL2186C) and dual
(EL2286C) topologies
• 3mA supply current (per amplifier)
• 250MHz -3dB bandwidth
• Low cost
• Fast disable
• Powers down to 0mA
• Single- and dual-supply operation
down to ±1.5V
• 0.05%/0.05° diff. gain/diff. phase
into 150Ω
• 1200V/µs slew rate
• Large output drive current:
100mA (EL2186C)
55mA (EL2286C)
• Also available without disable in
single (EL2180C), dual
(EL2280C) and quad (EL2480C)
• Lower power EL2170C/EL2176C
family also available (1 mA/
70MHz) in single, dual and quad
General Description
The EL2186C/EL2286C are single/dual current-feedback operational
amplifiers which achieve a -3dB bandwidth of 250MHz at a gain of +1
while consuming only 3mA of supply current per amplifier. They will
operate with dual supplies ranging from ±1.5V to ±6V, or from single
supplies ranging from +3V to +12V. The EL2186C/EL2286C also
include a disable/power-down feature which reduces current con-
sumption to 0mA while placing the amplifier output in a high
impedance state. In spite of its low supply current, the EL2286C can
output 55mA while swinging to ±4V on ±5V supplies. The EL2186C
can output 100mA with similar output swings. These attributes make
the EL2186C/EL2286C excellent choices for low power and/or low
voltage cable-driver, HDSL, or RGB applications.
For Single, Dual and Quad applications without disable, consider the
EL2180C (8-Pin Single), EL2280C (8-Pin Dual) or EL2480C (14-Pin
Quad). For lower power applications where speed is still a concern,
consider the EL2170C/El2176C family which also comes in similar
Single, Dual and Quad configurations. The EL2170C/EL2176C fam-
ily provides a -3dB bandwidth of 70MHz while consuming 1mA of
supply current per amplifier.
