The OP5330 module provides 16 single-ended analog output channels sampled at 1MS/s or 8 single-ended analog output channels sampled at 2MS/s, and produces values up to ±16V.
The maximum sampling rate is configurable through RT-LAB. See OP5330 16 AOUT- Dynamic sampling rate
It comes in two versions: the OP5330-1 and the OP5330-3.
The only difference between these two versions is the current limit specification.

Main Features

  • 16 or 8 single-ended analog output channels
  • 16-bit resolution
  • Simultaneous sampling at 1MS/s or 2MS/s
  • Configurable voltage range: ±5V, ±10V, ±16V (default)
  • Current limit : 15 or 35 mA
  • Factory-calibrated for each voltage range

Channel description

The module uses 8 dual-channel 16-bit resolution digital-to-analog converter (DAC). The channels are sampled at 1 MS/s, giving a total throughput of 16 MS/s, with all channels simultaneously sampled. In 8 channels mode, the sampling is 2 MS/s, giving a total throughput of 16 MS/s , with all channels simultaneously sampled.
The figure below represents a simplified schematic of one channel of the OP5330 module. It is composed of three stages:

  • The first stage consists of one gain DAC and one offset DAC. These DACs are used to apply the calibration values stored in an onboard EEPROM.
  • The second stage consists of a signal DAC, which converts the signal data value provided by the simulation, and combines it via an operational amplifier with the calibration gain.
  • The third stage consists of an operational amplifier that receives the final signal value and integrates it with the calibration offset.

Current/Voltage characteristics

The output voltage range can be set to ±5V, ±10V or ±16V by software. The default range is ±16 volts. The same range applies to all 16 channels of the module.

The maximum current per channel is either ±15mA (OP5330-3) or ±35mA (OP5330-1). 

Note: The OP5330-1 should be selected when long cables are needed to connect the OPAL-RT simulator and the external device.


  • The module is factory-calibrated to ensure that the output voltage has a ±20mV precision.

NOTE: A version of this board, the OP5330-1K2, intended for traveling wave applications, has had a modification made on the output voltage to ±4V forlower signal/noise ratio.

It is available in multiple versions with the following characteristics.

Typical Use Cases

The following diagram provides an example of a typical application using the OP5330. Analog output of either 15 or 35 (maximum) mA is directed to the ECU under test, where the analog input is processed by signal conditioning.
