The W83773G TR is a popular temperature sensor designed to provide precise and accurate temperature readings. It is an analog and digital output device which is capable of sensing temperatures from -40°C to +85°C (-104°F to +185°F). This sensor is typically used in applications such as medical, automotive, and industrial. It is frequently used in HVAC applications, as it can measure temperatures accurately and across a range of environments.

The W83773G TR is a very small device, manufactured to a size of only 8 mm ×8 mm ×2.3 mm, and includes an integrated temperature sensor (an NTC thermistor), a temperature alarm, and a digital output (for signal conditioning and interfacing). This makes the device simple to use and incredibly accurate.

The W83773G TR works according to the point-of-load principle. This means that the device is capable of sensing the temperature at a single point in the circuit. The thermistor is attached to a substrate and connected to the W83773G TR, with the thermistor sensing the temperature of the substrate. This makes it very accurate, as it reads the temperature of the substrate at a specific point, rather than making an average reading of the temperature of the whole circuit.

The W83773G TR includes a built-in temperature alarm, which triggers an alarm when the temperature reaches a specific threshold. This threshold can be manually adjusted based on the application and the user\'s requirements. The device also features a self-adaptive hysteresis structure, which allows the device to dynamically adjust the alarm threshold when temperatures fluctuate.

The digital output of the W83773G TR allows the device to be easily interfaced and connected to other devices, such as microcontrollers or signal conditioning devices. The output is configurable and can be set to either an open-collector CMOS output or an open-drain CMOS output. The output is also configurable in terms of resolution and accuracy, with the device capable of providing readings with a resolution of 0.1°C.

The W83773G TR is a highly reliable and precise temperature sensor, and is widely used in applications which require accurate temperature measurement. Its small size and easy-to-use design make it an ideal choice for applications of various sizes and complexity. The device\'s digital output, temperature alarm, and self-adaptive hysteresis features further increase its versatility and usability, and make it a popular choice for applications such as medical, automotive, and industrial.
