TCN75A - 2-Wire Serial Temperature Sensor
The TCN75A is a digital temperature sensor that converts temperatures between -40°C and +125°C to a digital word, with ±1°C (typ.) accuracy.
The TCN75A comes with user-programmable registers that provide flexibility for temperature-sensing applications. The register settings allow user-selectable, 0.5°C to 0.0625°C temperature measurement resolution, configuration of the power-saving Shutdown and One-shot (single conversion on command while in Shutdown) modes and the specification of both temperature alert output and hysteresis limits.
When the temperature changes beyond the specified limits, the TCN75A outputs an alert signal. The user has the option of setting the alert output signal polarity as an active-low or active-high comparator output for thermostat operation, or as temperature event interrupt output for microprocessor-based systems.
The TCN75A sensor has an industry standard 2-wire, I2C™ compatible serial interface, allowing up to eight devices to be controlled in a single serial bus. These features make the TCN75A ideal sophisticated multi-zone temperature-monitoring applications.
The TCN75AVOA713 is a SOIC (narrow) 2-Wire Serial Temperature Sensor that comes in 3300 piece reel.
