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.
