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 1.7 V to 5.5 V.

In the simplest mode of operation, the TMP1826 1-Wire interface, with an integrated 8-kV 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 V DD power pin also available for applications that may want to have a dedicated power supply.
