General Description

The EL2386C is a triple current-feedback operational amplifier which achieves a b3 dB bandwidth of 250 MHz at a gain of a1 while consuming only 3 mA of supply current per amplifier. It will operate with dual supplies ranging from g1.5V to g6V, or from single supplies ranging from a3V to a12V. The EL2386C also includes a disable/power-down feature which reduces current consumption to 0 mA while placing the amplifier output in a high impedance state. In spite of its low supply current, the EL2386C can output 55 mA while swinging to g4V on g5V supplies. These attributes make the EL2386C an excellent choice for low power and/or low voltage cable-driver, HDSL, or RGB applications.
