This document is the datasheet of low voltage temperature sensors tmp35/tmp36/tmp37. It provides the features and characteristics of the sensor, including operating voltage, accuracy, applications, etc.
The TMP35, TMP36 and TMP37 are low‑voltage, precision centigrade temperature sensors from Analog Devices. They provide a voltage output linearly proportional to temperature, require no external calibration, and operate from a single 2.7 V to 5.5 V supply. Typical accuracies are ±1 °C (F‑grade) or ±2 °C (G‑grade) at 25 °C, with very low quiescent current (<50 pA) and a shutdown current of 0.5 pA max.
The devices are offered in TO‑92, SOIC‑N and SOT‑23 packages, feature a shutdown pin for ultra‑low power, and include detailed specifications for absolute maximum ratings, thermal resistance, ESD protection, and typical performance characteristics such as output voltage, supply current, and response time.
| Supply Voltage Range | 2.7 V to 5.5 V |
|---|---|
| Output Voltage (TMP35) at 25 °C | 250 mV |
| Shutdown Current (max) | 0.5 pA |
| Quiescent Current | < 50 pA |
They operate from 2.7 V to 5.5 V.
The TMP36 provides a 750 mV output at 25 °C.
The shutdown current is limited to a maximum of 0.5 pA.
