Product Overview
The ADT75 is a 12-bit digital temperature sensor offering high accuracy with B grade accuracy of 1.0C from 0C to 70C and A grade accuracy of 2.0C from 25C to +100C. It features an SMBus/I2C-compatible interface and operates over a wide temperature range of 55C to +125C with a supply voltage from 3 V to 5.5 V. The sensor includes an overtemperature indicator and a low-power shutdown mode. Its compact size and low cost make it suitable for various applications including isolated sensors, environmental control, computer thermal monitoring, thermal protection, industrial process control, power-system monitors, and hand-held devices.
