NONLINEAR ANALOG SIGNAL PROCESSING

OPA688 UPGRADE

DESCRIPTION

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.

The OPA698 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

±10mV. The op amp operates linearly to within 20mV of the

output limit voltages.

Nonlinear analog signal processing will benefit from the

ability of the OPA698 to sharply transition from linear opera-

tion to output limiting. The quick recovery time supports

high-speed applications.

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 ensures that overdrive signals will be

transparent to the signal channel. Implementing the limiting

The OPA698 is available in an industry standard pinout SO-8

package. For higher gain, or transimpedance applications

requiring output limiting with fast recovery, consider the

OPA699.
