GENERAL DESCRIPTION

The ADT7420 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 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 to 1 (Register Address 0x03).

FEATURES

13- or 16-bit user selectable temperature-to-digital converter

Low drift silicon temperature sensor

No temperature calibration/correction required by user

Power saving 1 sample per second (SPS) mode

Fast first conversion on power-up of 6 ms

I2C-compatible interface

Operating temperature: ?40°C to +150°C

Operating voltage: 2.7 V to 5.5 V
