The TMP1826 is a high-accuracy, single-wire compatible digital output temperature sensor. The typical accuracy of this device is ±0.1°C across the temperature range of –20°C to +85°C. Figure 2-3 shows the bus-powered mode where the TMP1826 only requires a single connection and a ground return, which helps to simplify design and reduce cost by limiting the number of wires in the system. Alternatively, the VDD pin gives users the option to use a dedicated power supply for certain applications that may require it. This is seen in Figure 2-4. The TMP1826 also has integrated 8-kV IEC-61000-4-2 ESD protection on the data pin, which removes the need for any external protection components.
Figure 2-5 shows the accuracy of the TMP1826 across temperature. The data sheet minimum and maximum temperature error specifications are identified by the red lines on the graph, while the typical performance of the TMP1826 is shown in black. This device can provide another high-accuracy alternative to complicated RTD circuits.
