GENERAL DESCRIPTION
The AD8037-EP is a wide bandwidth, low distortion clamping
amplifier. The AD8037-EP is stable at a gain of two or greater. This
device allows the designer to specify a high (V
CH
) and low (V
CL
)
output clamp voltage. The output signal clamps at these specified
levels. Utilizing a unique patent pending CLAMPING™ input
clamp architecture, the AD8037-EP offers a 10× improvement in
clamp performance compared to traditional output clamping
devices. In particular, clamp error is typically 3 mV or less and
distortion in the clamp region is minimized. This product can be
used as a classical op amp or clamp amplifier.

Figure 1.
The AD8037-EP, which utilizes a voltage feedback architecture,
meets the requirement of many applications which previously
depended on current feedback amplifiers. The AD8037-EP exhibits
an exceptionally fast and accurate pulse response (16 ns to 0.01%),
extremely wide small-signal and large-signal bandwidths and
ultralow distortion. The AD8037-EP recovers from 2× clamp
overdrive within 1.5 ns. These characteristics position the
AD8037-EP ideally for driving as well as buffering flash and
high resolution ADCs.
In addition to traditional output clamp amplifier applications,
the input clamp architecture supports the clamp levels as
additional input to the amplifier. As such, in addition to static
dc clamp levels, signals with speeds up to 240 MHz can be
applied to the clamp pins. The clamp values can be set to any
value within the output voltage range provided that V
H
is greater
than V
L
. Due to these clamp characteristics, the AD8037-EP
can be used in nontraditional applications such as a full wave
rectifier, a pulse generator, or an amplitude modulator. These
novel applications are only examples of some of the diverse
applications which can be designed with input clamps.
Additional application and technical information can be found
in the AD8037 data sheet.
