This feature allows both the maximum positive (Vhigh) and negative (Vlow) output voltage levels to be established. This is useful in a number of applications in which "downstream" circuitry must be protected from overdriving 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 systems 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 second 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-performance design solution. Since the CLC501's current feedback design requ...
