TMP03/TMP04 is a low-cost serial digital output thermometer that generates a modulated serial digital output proportional to the temperature. It has an accuracy of 1.5°C (typical) from -25°C to +100°C, and can operate in the range of -40°C to +100°C, up to 150°C. It has a maximum power consumption of 6.5 mW and can operate at low voltage from 4.5 V to 7 V. It is suitable for applications such as isolated sensors, environmental control systems, computer thermal monitoring, thermal protection, industrial process control, and power system monitors.
The TMP03 and TMP04 are monolithic temperature detectors that provide a modulated serial digital output proportional to temperature. They operate from a low‑voltage supply (4.5 V‑7 V) and are available in TO‑92, SO‑8 and TSSOP‑8 packages.
