LMH6657/LMH6658
270MHz Single Supply, Single & Dual Amplifiers
General Description
The LMH6657/6658 are low-cost operational amplifiers that
operate from a single supply with input voltage range ex-
tending below the V. Based on easy to use voltage feed-
back 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 (AV = +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 Vto 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.
