Description and Introduction

Low Voltage Temperature Sensors The TMP37FS is a temperature sensor manufactured by Analog Devices Inc. (ADI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Temperature Range:** +5°C to +100°C  
- **Output Scale Factor:** 20 mV/°C  
- **Accuracy:** ±2°C (from +25°C to +100°C)  
- **Quiescent Current:** 50 µA (typical)  
- **Output Impedance:** 1 Ω (typical)  
- **Package Type:** TO-92 (3-pin)  

### **Descriptions:**  
- The TMP37FS is a low-voltage, precision centigrade temperature sensor.  
- It provides a voltage output that is linearly proportional to the Celsius temperature.  
- Unlike other temperature sensors, it does not require external calibration or signal conditioning.  
- Designed for low-power applications with minimal self-heating.  

### **Features:**  
- **Linear Output:** 20 mV/°C scaling eliminates the need for signal conditioning.  
- **Low Power Consumption:** Operates with a quiescent current of 50 µA.  
- **Wide Supply Range:** Compatible with 2.7V to 5.5V systems.  
- **No External Components Required:** Simplifies circuit design.  
- **Stable for Extended Temperatures:** Suitable for industrial and consumer applications.  

This information is based solely on the manufacturer's datasheet.

Application Scenarios & Design Considerations

Low Voltage Temperature Sensors

Alternative Part Number

  • LM35DZ --: Analog temperature sensor with 10mV/°C output, widely available and functionally similar to the TMP37 in many temperature-sensing applications.
  • LM335Z --: Precision analog temperature sensor with 10mV/K output, suitable as a direct functional substitute in many circuits.
  • AD590JH --: Current-output analog temperature sensor from the same manufacturer, usable as an alternative with minor circuit adjustment.
  • AD590JF --: Current-output temperature transducer from the same manufacturer family, offers similar temperature sensing performance with different output format.
