11.2 Typical Application

Figure 50 shows the basic connections for an independent, two-channel thermocouple measurement system when using the internal high-precision temperature sensor for cold-junction compensation. Apart from the thermocouples, the only external circuitry required are biasing resistors, first order low-pass, anti-aliasing filters, and a power supply decoupling capacitor.
