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.
Desired Gain (V/V) | RG (Ω) | Nearest 1% RG (Ω) |
|---|---|---|
1 | NC | NC |
2 | 50.00k | 49.9k |
5 | 12.50k | 12.4k |
10 | 5.556k | 5.62k |
20 | 2.632k | 2.61k |
50 | 1.02k | 1.02k |
100 | 505.1k | 511 |
200 | 251.3 | 249 |
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
