LMH6704
650 MHz Progammable Gain Buffer with Disable
General Description
The LMH
6704 is a very wideband, DC coupled progam-
mable 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 providing user programmable
gains of +1, +2 and 1 V/V. 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.
With a 650 MHz Small Signal Bandwidth (A
V
= +1), full
power gain flatness to 200 MHz, and excellent Differential
Gain and Phase, the LMH6704 is optimized for video appli-
cations. High resolution video systems will benefit from the
LMH6704’s ability to drive multiple video loads at low levels
of differential gain or differential phase distortion.
The LMH6704 is constructed with National’s proprietary high
speed complementary bipolar process using National’s
proven current feedback circuit architectures. It is available
in 8-Pin SOIC and 6-Pin SOT23 packages.
