250 MHz,三路电流反馈放大器
250MHz Triple Current Feedback Amplifier with Disable
The EL2386 is a triple current feedback 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 currentconsumption to 0mA while placing the amplifier output ina 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.
