The TC72 is a digital temperature sensor with an SPI‑compatible serial interface, offering 10‑bit resolution (0.25 °C/Bit) and high accuracy across a wide temperature range. It is available in compact 8‑pin MSOP and DFN packages and requires no external components beyond a decoupling capacitor.
The document lists electrical characteristics such as a 2.65‑5.5 V operating voltage, 250 µW continuous power consumption, 1 µA shutdown current, and detailed timing parameters for the SPI port. Typical applications include PCs, servers, storage devices, entertainment systems, and general‑purpose temperature monitoring.
| Operating Voltage Range | 2.65 V – 5.5 V |
|---|---|
| Resolution | 10‑bit (0.25 °C/Bit) |
| Temperature Accuracy (‑40 °C to +85 °C) | ±2 °C |
| Package Types | 8‑pin MSOP, 8‑pin DFN (3 × 3 mm) |
The TC72 can measure temperatures from –55 °C to +125 °C.
Data is shifted on the rising edge of SCK and clocked on the falling edge when CP = 0.
The sensor provides a 10‑bit conversion, giving a resolution of 0.25 °C per bit.
