Overview
Description
The TMP1075DR is designed for low power consumption, making it suitable for battery-operated devices. Its fast conversion time enhances responsiveness in applications requiring quick temperature monitoring. The sensor comes in a small, surface-mount package (SOIC-8), facilitating easy placement on printed circuit boards.
Applications for the TMP1075DR include environmental monitoring, industrial control systems, consumer electronics, and any system requiring precise thermal management. Its robust design, coupled with its digital interface, ensures it can be a reliable component in a wide variety of temperature-sensing applications.
Equivalent
1. LM75A from NXP or other manufacturers.
2. ADT7410 from Analog Devices.
3. MCP9808 from Microchip Technology.
4. LM75 from Texas Instruments (older version).
5. Si7051 from Silicon Labs.
These alternatives offer similar I2C interfaces and temperature sensing capabilities, but always verify specific requirements and compatibility for your application.
Features
The TMP1075DR is designed for low power consumption, with a current draw of just 10 µA during active measurement and 0.5 µA in shutdown mode, making it suitable for battery-powered devices. It features a fast conversion time of 125 ms, allowing for quick and efficient temperature monitoring.
Additionally, the sensor is available in a small, 8-pin SOIC package, which aids in space-constrained designs. Its programmable address allows for up to 32 devices on the same I²C bus. The TMP1075DR is ideal for applications in environmental monitoring, industrial systems, and consumer electronics.
Pinout
1. V+: Power supply voltage.
2. GND: Ground reference.
3. SDA: Serial Data Line. Used for bidirectional data transfer in I²C communication.
4. SCL: Serial Clock Line. Used to synchronize data transfer in I²C communication.
5. ALERT: An open-drain output that becomes active when the temperature exceeds a user-defined limit.
6. A0, A1, A2: Address pins. These pins are used to set the device's I²C address, allowing for multiple devices to exist on the same I²C bus.
The TMP1075DR is designed for precise temperature measurements and is suitable for various applications, including industrial automation, consumer electronics, and environmental monitoring, due to its wide operating temperature range and compatibility with the I²C communication protocol.
