Description
The EL2386 is a triple currentfeedback operational amplifier which achieves a -3dB bandwidth of 250MHz at a gain of +1 while consuming only 3mA of supply current per amplifier. It will operate with dual supplies ranging from ±1.5V to ±6V, or from single supplies ranging from +3V to +12V. The EL2386 also includes 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 EL2386 can output 55mA while swinging to ±4V on ±5V supplies. These attributes make the EL2386 an excellent choice for low power and/or low voltage cable-driver, HDSL, or RGB applications.
For single and dual applications, consider the EL2186/ EL2286. For single, dual, and quad applications without disable, consider the EL2180, EL2280, or EL2480, all in industry-standard pinouts. The EL2180 also is available in the tiny SOT-23 package, which is 28% the size of an SO8 package. 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.
