70 MHz 1 mA Current Mode Feedback Amplifiers

General Description

The EL2170C EL2270C EL2470C are single dual quad cur-

rent-feedback operational amplifiers which achieve a

bandwidth of 70 MHz at a gain of

1 mA of supply current per amplifier They will operate with

dual supplies ranging from

plies ranging from

current the EL2270C and the EL2470C can output 55 mA while

swinging to

100 mA with similar output swings These attributes make the

EL2170C EL2270C EL2470C excellent choices for low power

and or low voltage cable-driver HDSL or RGB applications

For applications where board space is extremely critical the

EL2170C is available in the tiny 5-Lead SOT23 package which

has a footprint 28% the size of an 8-Lead SOIC The EL2170C

EL2270C EL2470C are each also available in industry standard

pinouts in PDIP and SOIC packages

For 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

EL2180C El2186C family which also comes in similar Single

Dual Triple and Quad configurations The EL2180C EL2186C

family provides a

ing 3 mA of supply current per amplifier
