DESCRIPTION
The LMH6657/6658 are low-cost operational
amplifiers that operate from a single supply with input
voltage range extending below the V^−. Based on easy
to use voltage feedback topology and boasting fast
slew rate (700V/µs) 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° 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^− 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 SOT-23-5, SC70, SOIC-8, and VSSOP-8.
Refer to the Ordering Information section for
packaging options available for each device.
