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 ±15mV. The op amp operates linearly to within 30mV of the limits. The combination of narrow nonlinear range and low limiting offset allows the limiting voltages to be set within 100mV of the desired linear output range. A fast 2.4ns recovery from limiting ensures that overdrive signals will be transparent to the signal channel. Implementing the LIMITED OUTPUT RESPONSE 2.5 2.0 2.10 G = +6 VH = 2.0V VL = –2.0V 2.05 limiting function at the output, as opposed to the input, gives the specified limiting accuracy for any gain, and allows the OPA689 to be used in all standard op amp applications. Non-linear analog signal processing circuits will benefit from the OPA689’s sharp transition from linear operation to output limiting. The quick recovery time supports high speed applications. The OPA689 is available in an industry-standard pinout in PDIP-8 and SO-8 packages. For lower gain applications requiring output limiting with fast recovery, consider the OPA688.
