General Description

The EL2176CEL2276C are singledual current-feedback oper-

per amplifier They will operate with dual supplies ranging

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 EL2276C can output 55 mA while

100 mA with similar output swings These attributes make the

EL2176CEL2276C excellent choices for low power andor low

voltage cable-driver HDSL or RGB applications

For Single Dual and Quad applications without disable consid-

er the EL2170C (8-Pin Single)

EL2270C (8-Pin Dual) or

EL2470C (14-Pin Quad) For higher bandwidth applications

where low power is still a concern consider the EL2180C

El2186C family which also comes in similar Single Dual and

Quad configurations The EL2180CEL2186C family provides a

b

3 dB bandwidth of 250 MHz while consuming 3 mA of supply

current per amplifier
