FEATURES

DESCRIPTION

23

•

Wideband operation

The LMH™6704 is a very wideband, DC coupled

–

selectable gain buffer designed specifically for wide

–

dynamic range systems requiring exceptional signal

fidelity. The LMH6704 includes on chip feedback and

–

gain set resistors, simplifying PCB layout while

•

High output current ±90 mA

providing user selectable gains of +1, +2 and

−1 V/V.

•

Very low distortion

The LMH6704 provides a disable pin, which places

the amplifier in a high output impedance, low power

–

mode. The Disable pin may be allowed to float high.
