DESCRIPTION
MAS6503 is a 24 bit Analog-to-Digital Converter (ADC), which employs a delta-sigma (ΔΣ) conversion technique. The resolution for a signal range of 373 mV is 17.4 bits.
MAS6503 is designed especially to meet the requirement for low power consumption, thus making it an ideal choice for battery powered systems. Overall current consumption values of 18.3 µA (one conversion in a second at maximum resolution) or less can be achieved. The minimum supply voltage is as low as 1.8V.
