Analog-to-digital converters are digital circuits that convert analog signals into digital data. A specific type of ADC is the Sigma-Delta converter, which uses a single-bit quantizer in conjunction with a digital filter to achieve high resolution. The presented device is an 18-bit Analog to Digital Converter with a Sigma-Delta architecture, featuring two input channels and packaged in an 8-MSOP (8 Millimeter Small Outline Package) format.
