The TMP1826 is a high-accuracy, 1-Wire® compatible digital output temperature sensor with integrated 2Kb EEPROM and a wide operating temperature range from –55°C to +150°C. The TMP1826 provides a high accuracy of ±0.1°C (typical)/±0.2°C (maximum) across the temperature range of +10°C to +45°C. Each device comes with a factory programmed 64-bit unique identification number for addressing and NIST traceability. The TMP1826 supports both standard speed for legacy application and overdrive mode with 90-kbps data rate for low latency communication across a wide voltage range of 1.7V to 5.5V.

In the simplest mode of operation, the TMP1826 1-Wire® interface, with an integrated 8kV IEC-61000-4-2 ESD protection on the data pin, requires only a single connection and a ground return in bus powered mode, which simplifies and reduces cost by reducing the number of wires and external protection components. Additionally, there is the VDD power pin also available for applications that need to have a dedicated power supply.
