Features
Triple amplifier topology 3 mA supply current (per amplifier) 250 MHz b 3 dB bandwidth Low cost Fast disable Powers down to 0 mA Single- and dual-supply operation down to g 1 5V p 05% 0 05 Diff gain Diff 0 hase into 150X 1200V ms slew rate 5 arge output drive current L 5 mA Available in single (EL2186C) and dual (EL2286C) form Non-power down versions available in single dual and quad (EL2180C EL2280C EL2480C) Lower power EL2170C EL2176C family also available (1 mA 70 MHz) in single dual A nd quad a
General Description
The EL2386C is a triple current-feedback operational amplifier which achieves a b 3 dB bandwidth of 250 MHz at a gain of a 1 while consuming only 3 mA of supply current per amplifier It will operate with dual supplies ranging from g 1 5V to g 6V or from single supplies ranging from a 3V to a 12V 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 g 4V on g 5V supplies These attributes make the EL2386C an excellent choice for low power and or low voltage cable-driver HDSL or F RGB applications Eor Single and Dual applications consider the EL2186C L2286C For Single Dual and Quad applications without disable consider the EL2180C EL2280C or EL2480C all in industry standard pin outs The EL2180C 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 EL2170C EL2176C family which also comes in similar Single Dual and Quad configurations The EL2170C EL2176C family provides a b 3 dB bandwidth of 70 MHz while consumCg 1 mA of supply current per amplifier in
