LMH6723/LMH6724/LMH6725
Single/Dual/Quad 370 MHz 1 mA Current Feedback
Operational Amplifier
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 applica-
tions with its 0.03% and 0.11˚ differential gain and phase for
NTSC and PAL video signals. 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 perfor-
mance, 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 (TSSOP, 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 Na-
tional’s VIP10
