The OP4230-1 digital to analog converter (DAC) provides 16 single-ended digital output channels. Each channel uses a 16-bit resolution digital-to-analog converter.

Each OP4230-1 can sample up to 1 MS/s, giving a total throughput of 8 MS/s, all channels are simultaneously sampled. The onboard EEPROM provides offset and gain data adjustment written during the calibration process, as well as over-voltage protection.

By default, the maximum output signal is set to ±16 volts.


  • 16 single-ended analog output channels
  • All outputs are sampled simultaneously, up to 1 MS/s
  • 16-bit resolution
  • ±16 V voltage range output
  • ±15 mA maximum current per channel
  • Factory calibrated


The figure below represents a simplified schematic of one channel of the OP4230-1 module.

It is composed of three stages: the first stage consists of one gain DAC and one offset DAC; the second stage consists of a signal DAC with an operational amplifier that allows for gain adjustments; the third stage consists of an operational amplifier that receives final signal value and integrates the offset.
