The TMP1826 is a high-accuracy, single-wire compatible digital output temperature sensor with integrated 2-kbit EEPROM with a wide operating temperature range from –55°C to +150°C. The TMP1826 provides a high accuracy of ±0.1°C (typical)/±0.3°C (maximum) across the temperature range of –20°C to +85°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 single-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 VDD power pin also available for applications that may want to have a dedicated power supply.

The 2-kbit EEPROM on the TMP1826 allows the host to store application data in increments of 64 bits. With user programmable 256-bit page size write protection to avoid accidental overwrite, the EEPROM can be used as non-volatile, read-only memory. The four digital I/O pins are configurable for general purpose functions, temperature alert, or provide host to identify the position of the device on a shared bus.
