OP285GSZ-REEL7:  运算放大器SOIC-8封装

The OP-285 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 yeilds 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 OP-285 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 250 µV. This makes the OP-285 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 OP-285 one of the most accurate medium speed amplifiers available.

The combination of low noise, speed and accuracy can be used to build high speed instrumentation systems. CIrcuits such as instrumentation amplifiers, ramp generators, bi-quad filters and dc coupled audio systems are all practical with the OP-285.

For applications that require long term stability, the OP-285 has a guaranteed maximum long term drift specification.

The OP-285 is specified over the XIND-extended industrial- (-40°C to +85°C) temperature range. OP-285s are available in 8-pin plastic DIP and SOIC-8 surface mount packages.
