The OPA698 is a wide-band, unity-gain
stable voltage-feedback op amp that offers bipolar output voltage limiting. Two
buffered limiting voltages take control of the output when attempting to drive
beyond these limits. This new output limiting architecture holds the limiter offset
error to ±5mV.
The op amp
operates linearly to within 20mV of the output limit voltages. The combination of a
narrow nonlinear range and the low limiting offset allows the limiting voltages to
be set within 100mV of the desired linear output range. A fast 1ns recovery from
limiting provides overdrive signals that are 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 OPA698 to be used in all
standard op-amp applications.
Nonlinear analog signal processing
benefits from the ability of the OPA698 to sharply transition from linear operation
to output limiting. The quick recovery time supports high-speed applications.
The OPA698 is available in an
industry-standard pin-out SOIC-8 package. For higher gain, or transimpedance
applications that require output limiting with fast recovery, consider the OPA699.
