Description:

The GD30AD3340 device integrates a low-drift voltagereference and oscillator. The GD30AD3340 alsoincludes a programmable gain amplifier (PGA) and adigital comparator. These features, combined with awide operating supply voltage range, make theGD30AD3340 ideal for power-constrained and spaceconstrained sensor measurement applications.The GD30AD3340 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 accurate measurements of small and largesignals. The GD30AD3340 has an input multiplexer(MUX) that enables two pairs of differential inputmeasurements or four single-ended inputmeasurements. Digital comparators can be used inGD30AD3340 for undervoltage and overvoltagedetection.GD30AD3340 device is an I2C-compatible, 16-bit,high-precision, low-power analog-to-digitalconverter (ADC) in a small MSOP-10 package. GD30AD3340 can operate in both continuousconversion mode and single-shot mode. In single-shotmode, these devices automatically power down after aconversion; thus significantly reducing powerconsumption during idle periods.
