AD7414/AD7415 are complete temperature monitoring systems in 6-lead and 5-lead SOT-23 packages. They contain a bandgap reference temperature sensor, a 10-bit A/D converter, an SMBus/I2C-compatible serial interface, and a low-power mode for power management.
The AD7414 and AD7415 are complete temperature‑monitoring systems in compact SOT‑23 packages. They integrate a band‑gap temperature sensor and a 10‑bit ADC, providing a resolution of 0.25 °C and a typical accuracy of ±0.5 °C at 40 °C. The devices feature a 2‑wire SMBus/I²C‑compatible serial interface with selectable addresses and an optional ALERT output for over‑temperature detection.
These sensors operate from a 2.7 V to 5.5 V supply, draw only a few picoamps in shutdown, and support both one‑shot and automatic conversion modes. They are suited for applications such as hard‑disk drives, PCs, office equipment, cellular phones, and domestic appliances.
