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.
