The OPA688 is a wideband, unity gain stable voltage-feedback op amp that offers bipolar output voltage limiting. Two buffered limiting voltages take control of the output when it attempts to drive beyond these limits. This new output limiting architecture holds the limiter offset error to 15 mV. The op amp operates linearly to within 30 mV of the output limit voltages. The combination of narrow nonlinear range and low limiting offset allows the limiting voltages to be set within 100 mV of the desired linear output range. A fast 2.4-ns recovery from limiting ensures that overdrive signals will be transparent to the signal channel. Implementing the limiting function at the output, as opposed to the input, gives the specified limiting accuracy for any gain, and allows the OPA688 to be used in all standard op amp applications.
