The document describes the technical specifications and features of the ADT7408 digital temperature sensor, including a 12-bit temperature-to-digital converter, ±2°C accuracy, operating temperature range of -20°C to +125°C, etc.
The ADT7408 is a ±2°C accurate, 12-bit digital temperature sensor designed to comply with JEDEC standard JC-42.4 for mobile platform memory modules. It features an open-drain EVENT# output that can function as either a comparator or an interrupt pin.
| Temperature Sensor Accuracy (C Grade) | ±2.0 °C |
|---|---|
| ADC Resolution | 12 Bits |
| Temperature Conversion Time | 60 ms |
| Supply Voltage Range | 3.0 V to 3.6 V |
| Operating Temperature Range | -20°C to +125°C |
The local sensor accuracy for C Grade is ±2.0 °C within the active range.
The device operates from a supply voltage of 3.0 V to 3.6 V.
The EVENT# output is active when the monitoring temperature exceeds a critical programmable limit or falls outside an alarm window.
