16位數(shù)字I2C溫度傳感器adt7410數(shù)據(jù)表

　　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 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 I 2 C 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. 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.
