Replacing output clamping op amps with input clamping amps

Posted: 16 Jul 2010     Print Version  Bookmark and Share

Keywords:clamping amps  op amps  analogue signal 

Various systems like ultrasound and imaging systems have instances where the analogue signal might suddenly spike to a voltage extreme. But many downstream circuits like A/D drivers place restrictions on the analogue input signal levels to maintain their performance.

These devices can draw excessive current in an overdrive condition or else be driven into a region of saturation, which will have a long recovery time. Various clamp amps can be used in these systems to restrict signal excursions at their outputs to protect downstream devices. So far, most of the clamping amplifiers have relied upon an output clamping architecture and are called output clamp amps (OCAs). A new architecture called an input clamp amp (ICA) offers superior clamping accuracy and lower distortion.
