EL2170C/EL2270C/EL2470C  
70 MHz/1 mA Current Mode Feedback Amplifiers  
Features  
General Description  
The EL2170C/EL2270C/EL2470C are single/dual/quad cur-  
# Single (EL2170C), dual  
(EL2270C) and quad (EL2470C)  
topologies

rent-feedback operational amplifiers which achieve a 3 dB  
bandwidth of 70 MHz at a gain of 1 while consuming only  
a
1 mA of supply current per amplifier. They will operate with  
g
plies ranging from 3V to 12V. In spite of their low supply  
current, the EL2270C and the EL2470C can output 55 mA while

amplifier)

dual supplies ranging from 1.5V to 6V, or from single sup-

swinging to 4V on 5V 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.  
# Low cost

operation down to 1.5V  
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  
b
family provides a 3 dB bandwidth of 250 MHz while consum-  
ing 3 mA of supply current per amplifier.

# Higher speed EL2180C/EL2186C  
family also available (3 mA/  
250 MHz) in single, dual and  
quad
