OP285GSZ Datasheet PDF - ADI

The OP285GSZ is a precision high speed dual Operational 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 drift of a bipolar amplifier. Input offset voltage is laser-trimmed and guaranteed less than 250µV. This makes the OP285 useful in DC coupled or summing applications without the need for special selections or the added noise of additional offset adjustment circuitry. Slew rates of 22V/µs and a bandwidth of 9MHz make the OP285 one of the most accurate medium speed amplifiers available.
