eneral Description
The EL2170C EL2270C EL2470C are single dual quad current-feedback operational amplifiers which achieve a b 3 dB bandwidth of 70 MHz at a gain of a 1 while consuming only 1 mA of supply current per amplifier They will operate with dual supplies ranging from g 1 5V to g 6V or from single supplies ranging from a 3V to a 12V In spite of their low supply current the EL2270C and the EL2470C can output 55 mA while swinging to g 4V on g 5V supplies The EL2170C can output 100 mA with similar output swings These attributes make the EL2170C EL2270C EL2470C excellent choices for low power F and or low voltage cable-driver HDSL or RGB applications or applications where board space is extremely critical the EL2170C is available in the tiny 5-Lead SOT23 package which E has a footprint 28% the size of an 8-Lead SOIC The EL2170C L2270C EL2470C are each also available in industry standard F pinouts in PDIP and SOIC packages or Single and Dual applications with disable consider the EL2176C (8-Pin Single) or EL2276C (14-Pin Dual) For higher speed applications where power is still a concern consider the D EL2180C El2186C family which also comes in similar Single ual Triple and Quad configurations The EL2180C EL2186C family provides a b 3 dB bandwidth of 250 MHz while consumCg 3 mA of supply current per amplifier in
