8.4 Typical Application

Figure 68 shows a three-terminal programmable-logic controller (PLC) design for the INA828. 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.
