250MHz/3mA Current Mode Feedback
Amp w/Disable
The EL2186/EL2286 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 EL2186/EL2286
also include a disable/power-down feature which reduces
current consumption to 0mA while placing the amplifier
output in a high impedance state. In spite of its low supply
current, the EL2286 can output 55mA while swinging to ±4V
on ±5V supplies. The EL2186 can output 100mA with similar
output swings. These attributes make the EL2186/EL2286
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 EL2180 (8-Pin Single), EL2280 (8-Pin Dual) or
EL2480 (14-Pin Quad). For lower power applications where
speed is still a concern, consider the EL2170/EL2176 family
which also comes in similar Single, Dual and Quad
configurations. The EL2170/EL2176 family provides a -3dB
bandwidth of 70MHz while consuming 1mA of supply current
per amplifier.
