EL2276 Data Sheet May 6, 2005 FN7054.1 70MHz/1mA Current Mode Feedback Amp Features w/Disable Dual topology The EL2276 is a dual current-feedback operational amplifier 1mA supply current (per amplifier) which achieves a -3dB bandwidth of 70MHz at a gain of +1 while consuming only 1mA of supply current per amplifier. It 70MHz -3dB bandwidth will operate with dual supplies ranging from 1.5V to 6V, or Low cost from single supplies ranging from +3V to +12V. The EL2276 also includes a disable/power-down feature which reduces Fast disable current consumption to 0mA while placing the amplifier Powers down to 0mA output in a high impedance state. In spite of its low supply Single- and dual-supply operation down to 1.5V current, the EL2276 can output 55mA while swinging to 4V on 5V supplies. These attributes make the EL2276 0.15%/0.15 diff. gain/diff. phase into 150 excellent choice for low power and/or low voltage cable- 800V/s slew rate driver, HDSL, or RGB applications.
