LMH6723/LMH6724/LMH6725 Single/Dual/Quad 370 MHz 1 mA Current Feedback Op Amp

May 2004

General Description

The LMH6723/LMH6724/LMH6725 provides a 260 MHz
small signal bandwidth at a gain of +2 V/V and a 600 V/µs
slew rate while consuming only 1 mA from

The LMH6723/LMH6724/LMH6725 supports video applica­tions with its 0.03% and 0.11˚ differential gain and phase
errors for NTSC and PAL video signals while driving a back
terminated 75Ω load. The LMH6723/LMH6724/LMH6725
also offers a flat gain response of 0.1 dB to 100 MHz.
Additionally, the LMH6723/LMH6724/LMH6725 can deliver
110 mA of linear output current. This level of performance, as
well as a wide supply range of 4.5 to 12V, makes the
LMH6723/LMH6724/LMH6725 an ideal op amp for a variety
of portable applications. The LMH6723/LMH6724/
LMH6725’s small packages (SOIC & SOT23), low power
requirement and high performance, allow the LMH6723/
LMH6724/LMH6725 to serve a wide variety of portable ap­plications.

The LMH6723/LMH6724/LMH6725 is manufactured in Na­tional’s VIP
