. Based on easy to use voltage feed-
back topology and boasting fast slew rate (700V/碌s) and
high speed (140MHz GBWP), the LMH6657 (Single) and
LMH6658 (dual) can be used in high speed large signal
applications. These applications include instrumentation,
communication devices, set-top boxes, etc.
With a -3dB BW of 100MHz (A
V
= +2) and DG & DP of 0.03%
& 0.10藲 respectively, the LMH6657/6658 are well suited for
video applications. The output stage can typically supply
80mA into the load with a swing of about 1V from either rail.
For Industrial applications, the LMH6657/6658 are excellent
cost-saving choices. Input referred voltage noise is low and
the input voltage can extend below V
鈭?/div>
to ease amplification
of low level signals that could be at or near the system
ground. With low distortion and fast settling, LMH6657/6658
can provide buffering for A/D and D/A applications.
The LMH6657/6658 versatility and ease of use is extended
even further by offering these high slew rate , high speed Op
Amps in miniature packages such as SOT23-5, SC70,
SOIC-8, and MSOP-8. Refer to the Ordering Information
section for packaging options available for each device.
