The OP285 is a precision high-speed amplifier featuring theButler Amplifier front-end. This new front-end designcombines the accuracy and low noise performance of bipolartransistors with the speed of JFETs. This yields an amplifierwith high slew rates, low offset and good noise performance atlow supply currents. Bias currents are also low compared tobipolar designs.
The OP285 offers the slew rate and low power of a JFETamplifier combined with the precision, low noise and low driftof a bipolar amplifier. Input offset voltage is laser-trimmed andguaranteed less than 250 μV. This makes the OP285 useful indc-coupled or summing applications without the need forspecial selections or the added noise of additional offsetadjustment circuitry. Slew rates of 22 V/μs and a bandwidth of9 MHz make the OP285 one of the most accurate mediumspeed amplifiers available.
The combination of low noise, speed and accuracy can be usedto build high speed instrumentation systems. Circuits such asinstrumentation amplifiers, ramp generators, bi-quad filters anddc-coupled audio systems are all practical with the OP285. Forapplications that require long term stability, the OP285 has aguaranteed maximum long term drift specification.
The OP285 is specified over the XIND—extended industrial—(−40°C to +85°C) temperature range. The OP285 is available inan 8-lead SOIC_N surface mount package.
