Description:

GD30AD3640 device is an I2C-compatible, 24-bit,high-precision, low-power analog-to-digitalconverter (ADC) in a small MSOP-10 package.The GD30AD3640 device integrates a low-drift voltagereference and oscillator. The GD30AD3640 alsoincludes a programmable gain amplifier (PGA) and adigital comparator. These features, combined with awide operating supply voltage range, make theGD30AD3640 ideal for power -constrained and spaceconstrained sensor measurement applications.The GD30AD3640 can perform conversions at datarates up to 1000 samples per second (SPS). The PGAprovides an input range from ±64 mV to ±6.144 V,enabling precise measurement of large and smallsignals. The GD30AD3640 has an input multiplexer(MUX) that enables two pairs of differential inputmeasurements or four single-ended inputmeasurements. Digital comparators can be used in theGD30AD3640 for undervoltage and overvoltagedetection.The GD30AD3640 can operate in either continuousconversion mode or single-shot mode. In single-shotmode, the devices automatically power down after oneconversion; thus significantly reducing powerconsumption during idle periods.
