±1°C Accurate, 12-Bit Digital

Temperature Sensor

ADT75

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 3.0 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.
