Integrators GENERAL DESCRIPTION The OP285 is a precision high-speed amplifier featuring the
Butler Amplifier front-end. This new front-end design combines the accuracy and low noise performance of bipolar
transistors with the speed of JFETs. This yields an amplifier
with high slew rates, low offset and good noise performance
at low supply currents. Bias currents are also low compared
to bipolar designs.
The OP285 offers the slew rate and low power of a JFET
amplifier combined with the precision, low noise and low …
