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 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 OP285. For

applications that require long term stability, the OP285 has a

guaranteed 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 in

an 8-lead SOIC_N surface mount package.

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 250 μV. 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 22 V/μs and a bandwidth of

9 MHz make the OP285 one of the most accurate medium

speed amplifiers available.
