EL2176, EL2276
70MHz/1mA Current Mode Feedback Amp
w/Disable
The EL2176/EL2276 are single/dual
current-feedback operational
amplifiers which achieve a -3dB
bandwidth of 70MHz at a gain of +1 while consuming only
1mA 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 EL2176/EL2276
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 EL2276 can output 55mA while swinging to ±4V
on ±5V supplies. The EL2176 can output 100mA with similar
output swings. These attributes make the EL2176/EL2276
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 EL2170 (8-Pin Single), EL2270 (8-Pin Dual) or
EL2470 (14-Pin Quad). For higher bandwidth applications
where low power is still a concern, consider the
EL2180/EL2186 family which also comes in similar Single,
Dual and Quad configurations. The EL2180/EL2186 family
provides a -3dB bandwidth of 250MHz while consuming
3mA of supply current per amplifier.
