SBOS959C December 2018 – June 2020 INA819
Figure 69 shows a three-pin programmable-logic controller (PLC) design for the INA819. This PLC reference design accepts inputs of ±10 V or ±20 mA. The output is a single-ended voltage of 2.5 V ±2.3 V (or 200 mV to 4.8 V). Many PLCs typically have these input and output ranges.
