CLC501
High Speed, Output Clamping Op Amp
General Description
The CLC501 is a high speed current-feedback op amp with
the unique feature of output voltage clamping. This feature
allows both the maximum positive (V
HIGH) and negative
(V
LOW) output voltage levels to be established. This is useful
in a number of applications in which “downstream” circuitry
must be protected from over driving input signals. Not only
can this prevent damage to downstream circuitry, but can
also reduce time delays since saturation is avoided. The
CLC501’s very fast 1ns overload/clamping recovery time is
useful in applications in which information containing signals
follow overdriving signals.
Engineers designing high resolution, subranging A/D sys-
tems have long sought an amplifier capable of meeting the
demanding requirements of the residue amplifier function.
Amplifiers providing the residue function must not only settle
quickly, but recover from overdrive quickly, protect the sec-
ond stage A/D, and provide high fidelity at relatively high gain
settings. The CLC501, which excels in these areas, is the
ideal design solution in this onerous application. To further
support this application, the CLC501 is both characterized
and tested at a gain setting of +32–the most common gain
setting for residue amplifier applications.
The CLC501’s other features provide a quick, high perfor-
mance design solution. Since the CLC501’s current feed-
back design requires no external compensation, designers
need not spend their time designing compensation net-
works. The small 8-pin package and low, 180mW power
consumption make the CLC501 ideal in numerous applica-
tions having small power and size budgets.
The CLC501 is available in several versions to meet a
variety of requirements. A three letter suffix determines the
version:
