Product Description
ADT75: 12-Bit Digital Temperature Sensor
The ADT75 is a high-accuracy, 12-bit digital temperature sensor designed for a wide range of monitoring and control applications. It features an SMBus/I2C-compatible interface and operates over a broad temperature range from -55C to +125C. With its precise temperature measurement capabilities, low power consumption in shutdown mode, and compact package options, the ADT75 is ideal for environmental control, computer thermal monitoring, industrial process control, and power-system monitoring.
Product Description
- Accurate Temperature Measurement: Features a 12-bit temperature-to-digital converter for precise readings.
- B Grade Accuracy: 1.0C from 0C to 70C.
- A Grade Accuracy: 2.0C from 25C to +100C.
- Wide Operating Range: Operates from -55C to +125C.
- Flexible Power Supply: Operates from 3 V to 5.5 V.
- Overtemperature Indicator: Provides an alert for overtemperature conditions.
- Low Power Consumption: Offers a shutdown mode for reduced power usage (typically 3 A at 3.3 V).
- High Integration: On-chip temperature sensor for accurate ambient temperature measurement.
- High Resolution: Temperature resolution of 0.0625C.
- Multi-Device Capability: Supports connecting up to eight ADT75s to a single SMBus/I2C bus.
