The TMP20 is a CMOS, precision analog output temperature sensor available in the tiny SOT563 package. The TMP20 operates from –55°C to +130°C on a supply voltage of 2.7V to 5.5V with a supply current of 4µA. Operation as low as 1.8V is possible for temperatures between +15°C and +130°C. The linear transfer function has a slope of –11.77mV/°C (typ) and has an output voltage of 1.8639V (typ) at 0°C. The TMP20 has a ±2.5°C accuracy across the entire specified temperature range of –55°C to +130°C.
The TMP20 4µA (max) supply current limits self-heating of the device to less than 0.01°C. When V+ is less than 0.5V, the device is in shutdown mode and consumes less than 20nA (typ).
The TMP20 is available in either a 5-lead SC70 or 6-lead SOT563 package, reducing the overall board space required.
