ADT7420

The ADT7420 is a high accuracy digital temperature sensor offering breakthrough performance over a wide industrial range, housed in a 4 mm × 4 mm LFCSP package. It contains an internal band gap reference, a temperature sensor, and a 16-bit ADC to monitor and digitize the temperature to 0.0078°C resolution. The ADC resolution, by default, is set to 13 bits (0.0625°C). The ADC resolution is a user programmable mode that can be changed through the serial interface. The ADT7420 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 ADT7420 has a shutdown mode that powers down the device and offers a shutdown current of typically 2.0 μA at 3.3 V. The ADT7420 is rated for operation over the −40°C to +150°C temperature range. Pin A0 and Pin A1 are available for address selection, giving the ADT7420 four possible I2 C addresses. The CT pin is an opendrain output that becomes active when the temperature exceeds a programmable critical temperature limit. The INT pin is also an open-drain output that becomes active when the temperature exceeds a programmable limit. The INT pin and CT pin can operate in comparator and interrupt event modes.

With high resolution chip imaging packed in BrigenOne, you can determinate the region to be analyzed the schematics inside

• If you decide to perform a circuit analysis, we will provide a complete delivery, including BrigenOne, EDIF format schematics, and PDF file
• The project is still in the "evaluation" phase, and the work scope is open to discussing.
• The information we provide about this project will be quite accurate because we have completed high-resolution wafer images of each layer.
• The quotation for this project DOES NOT include high-resolution chip images packaged in BrigenOne. Please contact us to get a quote
• If you decide to perform a circuit analysis with a price exceeding US$10,000, we will provide a 25% discount on the cost of chip imaging; for circuit analysis above US$20,000, we will discount 50% of the cost of chip imaging.
