General Description
The EL2170C EL2270C EL2470C are single dual quad cur-
rent-feedback operational amplifiers which achieve a ^b3 dB
bandwidth of 70 MHz at a gain of ^a1 while consuming only
1 mA of supply current per amplifier They will operate with
dual supplies ranging from g1 5V to g6V or from single sup-
plies ranging from ^a3V to ^a12V In spite of their low supply
current the EL2270C and the EL2470C can output 55 mA while
swinging to g4V on g5V supplies The EL2170C can output
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 ^b3 dB bandwidth of 250 MHz while consum-
ing 3 mA of supply current per amplifier
