GENERAL DESCRIPTION
The ADT7320 is a high accuracy digital temperature sensor offering breakthrough performance over a wide industrial range, housed in an LFCSP package. It contains a band gap temperature reference and a 13-bit analog-to-digital converter (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 0x01).
FEATURES
Temperature accuracy ±0.25°C from −20°C to +105°C
