OP4240-1 - 16 Analog Inputs

The OP4240-1 module provides 16 differential analog input channels. Each channel uses a 16-bit resolution analog-to-digital converter. By default, the maximum input signal is set to ±20 volts.


  • 16 differential analog input channels
  • All inputs are sampled simultaneously for additional simulation They can be sampled up to 400 kS/s
  • 16-bit resolution
  • ±20V input range


The figure below represents a simplified schematic of one channel of the OP4240-1 modules. It is composed of three stages: the first stage consists of one operational amplifier that works in differential input mode and permits gain adjustment; the second stage, the level shifter, forms the signal for the A/D converter input; the third stage occurs after the conversion to the digital type, as the signal is sent to the carrier board.

Differential input ADC circuit

The OP4240-1 cassette includes the OP5340-1 mezzanine card.
