The ADT7410 is a high accuracy digital temperature sensor in a narrow SOIC package. It contains a band gap temperature reference and a 13 bit ADC to monitor and digitize the temper-ature to a 0.0625°C resolution. The ADC resolution, by default, is set to 13 bits (0.0625°C). This can be changed to 16 bits (0.0078°C) by setting Bit 7 in the configuration register (Register Address 0x03).
The ADT7410 is guaranteed to operate over supply voltages from 2.7 V to 5.5 V. Operating at 3.3 V, the average supply current is typi-cally 210 μA. The ADT7410 has a shutdown mode that powers down the device and offers a shutdown current of typically 2 μA. The ADT7410 is rated for operation over the −55°C to +150°C temperature range.
Pin A0 and Pin A1 are available for address selection, giving the ADT7410 four possible I2C® addresses. The CT pin is an open-drain output that becomes active when the temperature exceeds a programmable critical temperature limit. The default critical temperature limit is 147°C. The INT pin is also an open-drain output that becomes active when the temperature exceeds a programmable limit. The INT and CT pins can operate in either comparator or interrupt mode.
