Description and Introduction

Voltage Output Temperature Sensors The TMP35 is a precision analog output temperature sensor manufactured by Analog Devices (AD). 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:** -40°C to +125°C  
- **Output Voltage Scale Factor:** 10 mV/°C  
- **Accuracy:** ±1°C (typical) at +25°C, ±2°C (max) from -40°C to +125°C  
- **Quiescent Current:** < 50 µA  
- **Output Impedance:** < 1 Ω (for loads up to 1 mA)  
- **Line Regulation:** 0.1 mV/V (typical)  
- **Load Regulation:** 0.1 mV/mA (typical)  

### **Description:**  
The TMP35 is a low-voltage, precision centigrade temperature sensor that provides a voltage output linearly proportional to the Celsius temperature. It does not require external calibration and is designed for single-supply operation. The sensor is suitable for a wide range of applications, including environmental monitoring, industrial control, and battery-powered systems.  

### **Features:**  
- **Linear Output:** 10 mV/°C scale factor  
- **Wide Operating Range:** -40°C to +125°C  
- **Low Power Consumption:** < 50 µA quiescent current  
- **Single-Supply Operation:** 2.7V to 5.5V  
- **No External Calibration Required**  
- **Low Output Impedance:** Drives loads up to 1 mA  
- **Stable with Capacitive Loads:** Does not require additional components for stability  

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

Application Scenarios & Design Considerations

Voltage Output Temperature Sensors

Alternative Part Number

  • LM35DZ --: Industry-standard analog temperature sensor with 10 mV/°C output, direct drop-in functional equivalent to TMP35 in most circuits.
  • LM50 --: Analog temperature sensor with similar 10 mV/°C slope and wide supply range, suitable replacement when slight offset differences are acceptable.
  • AD590 --: Current-output temperature transducer usable as an alternative with a simple resistor conversion, offering wide temperature range and good accuracy.
  • AD22100 --: Analog voltage-output temperature sensor from the same manufacturer family, offering comparable accuracy and linearity for temperature monitoring.
