±1°C Accurate, 12-Bit Digital Temperature Sensor

Manufactured by:

Product Details

The ADT75 is a complete temperature monitoring system in 8-lead MSOP and SOIC packages. It contains a band gap temperature sensor and 12-bit Aanalog-to-digital converter (ADC) to monitor and digitize the temperature to a resolution of 0.0625°C. The ADT75 is pin and register compatible with the LM75 and AD7416.

The ADT75 is specified for operation at supply voltages from 2.7 V to 5.5 V. Operating at 3.3 V, the average supply current is typically 200 μA.

The ADT75 offers a shutdown mode that powers down the device and this mode gives a shutdown current of typically 3 μA. The ADT75 is rated for operation over the –55°C to +125°C temperature range.

The A0, A1, and A2 pins are available for address selection. The OS/ALERT pin is an open-drain output that becomes active when temperature exceeds a programmable limit. The OS/ALERT pin can operate in either comparator or interrupt mode.

Product Highlights

  1. On-chip temperature sensor allows an accurate measurement of the ambient temperature. The measurable temperature range is −55°C to +125°C.
  2. Supply voltage is 2.7 V to 5.5 V.
  3. Space-saving, 8-lead MSOP and 8-lead SOIC.
  4. Temperature accuracy is ±1°C maximum.
  5. Temperature resolution is 0.0625°C.
  6. Shutdown mode reduces the current consumption to 3 μA typical.
  7. Connect up to eight ADT75s to a single SMBus/I2C bus.

Product Details

The Wireless Sensor Network (WSN) demo platform is a flexible, modular system for evaluating all aspects of a WSN. It offers both an out-of-the-box demonstration system, and can also be used as a development platform. It contains all of the hardware and software necessary to implement a plug-and-play WSN.  The hardware includes a base station node along with multiple sensor nodes that support many different sensors. The system is flexible in that sensors can be connected in any combination to any of the sensor nodes. The out-of-the-box utility of the WSN development kits significantly reduces the time and effort required to move a customer’s design from proof-of-concept phase to production release through the marriage of three Multi-Sensor Node Boards, a gateway connector, an emulator platform, and a full featured software package.
