The OP8E09 module is designed as a buffer amplifier for four (4) low-voltage inputs signals coming from the unit under test. It also provides global isolation between the unit under test and the simulator.

Features

  • 4 channels
  • Global isolation
  • Individually configurable gain
  • Maximum input range ±16V

Channel Description

The gain of each channel can be increased to reach the full ± 16V output range of the OP5340 mezzanine of the simulator by using resistors to adjust R-optional. 

Resistor Settings

An R-optional socket is available for each channel as shown below. The following table gives with commonly used gains and resistor values to select appropriate resistors.

With the numbers above, by installing, for example, a 5.62KΩ resistor on the R-optional socket, you change the gain from 1 to 10. A ±1.5V input signal will then be seen as a ±15V signal.

Maximum Frequency

The maximum frequency without slew-rate induced distortion is 50KHz
