The AD7414 is a complete temperature monitoring system in a 6-pin SOT-23 package. It contains a bandgap temperature sensor and 10-bit ADC to monitor and digitize the temperature reading to a resolution of 0.25°C.
The AD7414 provides a two-wire serial interface, which is compatible with SMBus and I2C interfaces. On-chip registers can be programmed with high and low temperature limits. An ALERT output (SMBus compatible) becomes active when the high temperature limit is exceeded.
The part comes in four versions, the AD7414-0, AD7414-1, AD7414-2 and the AD7414-3. The AD7414-0 and AD7414-1 versions allow for the choice of three different SMBus addresses each. All four versions combined give a possibility of eight different I2C addresses for the AD7414.
The AD7414's 2.7 V supply voltage, low supply current, serial interface and small package size, make it ideal for a variety of applications, including personal computers, cellular phones, office equipment and domestic appliances.
Also see the AD7415, which a sister part to the AD7414 in a 5-Lead SOT-23. This part does not have the SMBus Alert Functionality.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
The AD7414/AD7415 evaluation board allows the AD7414/AD7415 digital temperature sensor to be quickly and easily evaluated using a PC. Using the evaluation board and its accompanying software, the AD7414/AD7415 evaluation board can be interfaced to a PC through its USB connection. The drivers will work on 32-bit Windows 7 machines.
Please note: This Evaluation software does not run on Windows 8 or Windows 10 (USB driver is non-compliant with OS >Windows 7).
