It contains a band gap temperature reference and a 13-bit ADC to monitor and digitize the temperature 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 typically 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 opendrain output that becomes active when the temperature exceeds a programmable critical temperature limit.
The default critical temperature limit is 147°C.
