Getting 15-Bit Resolution by Multi-Channel Expansion Oversampling of 12-Bit ADC

Introduction: Increasing The Resolution of Analog-to-Digital Conversion by Oversampling Every analog-to-digital conversion is designed for specific resolution depending on the bit (binary digit) width of the conversion. For example, a 10 bit ADC with 5V reference would have 5V/1024 resolution or about 4.883 mV. The intrinsic error related to the resolution is the digital-quantization error  of ±0.5 bit (or 2.441 […]
