DESCRIPTION
The OPA699 is a wideband, voltage-feedback op amp that
offers bipolar output voltage limiting, and is stable for gains
≥
+4. 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
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 1ns 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 OPA699 to be used in
all standard op amp applications.
Nonlinear analog signal processing circuits will benefit from
the OPA699 sharp transition from linear operation to output
limiting. The quick recovery time supports high-speed applica-
tions.
The OPA699 is available in an industry-standard pinout in an
SO-8 package. For lower gain applications requiring output
limiting with fast recovery, consider the OPA698.
