With the recently introduced wide-band op amp OPA622,
Burr-Brown has reached a new height in op amp design. In
the past, engineers designing a circuit with feedback had to
choose between voltage and current feedback according to
the requirements of their particular applications. Both feedback
types involve a trade-off. The current-feedback structures
available up to now use their symmetrical circuit
design and short feedback loop to process wide-band analog
signals, while the traditional voltage-feedback amplifiers
provide more optimized DC performance but slow down the
signal processing rate. But with the OPA622, an IC is
available that can be configured for both modes.
