DESCRIPTION
The OPA688 is a wideband, unity gain stable voltage
feedback op amp that offers bipolar output voltage lim-
iting. 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 output limit voltages.
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 sig-
nals will be transparent to the signal channel. Imple-
menting 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.
Non-linear analog signal processing will benefit from
the OPA688’s sharp transition from linear operation to
output limiting. The quick recovery time supports high
speed applications.
The OPA688 is available in an industry standard pinout
in PDIP-8 and SO-8 packages. For higher gain, or
transimpedance applications requiring output limiting
with fast recovery, consider the OPA689.
