Description:

GD30AD3344 device is a SPI -compatible 16-bithigh-precision, low-power analog-to-digital converter (ADC) in a small and MSOP-10 package. TheGD30AD3344 device integrates a low-drift voltagereference and oscillator. The GD30AD3344 alsoincludes a programmable gain amplifier (PGA) and adigital comparator. These features, combined with awide operating supply voltage range, make theGD30AD3344 ideal for power -constrained and spaceconstrained sensor measurement applications.The GD30AD3344 can perform conversions at datarates up to 1000 samples per second (SPS). The PGAprovides an input range from ±64mV to ±6.144V,enabling accurate measurement of large and smallsignals. The GD30AD3344 has an input multiplexer(MUX) that enables two pairs of differential inputmeasurements or four single-ended inputmeasurements. Digital comparators can be used in theGD30AD3344 for undervoltage and overvoltagedetection.The GD30AD3344 can operate in either continuousconversion mode or single-shot mode. In single-shotmode, these devices automatically power down afterone conversion; thus significantly reducing powerconsumption during idle periods.
