SBASAQ6 April 2024 ADS9813
ADVANCE INFORMATION
The ADS9813 incorporates eight, simultaneous sampling, 18-bit successive approximation register (SAR) analog-to-digital converters (ADCs). The device has a total of eight analog input pairs. The ADC digitizes the voltage difference between the analog input pairs AINxP – AINxM. Figure 6-1 shows the simplified circuit schematic for each analog input channel. This figure also shows the input clamp protection circuit, programmable gain amplifier (PGA), low-pass filter, high-speed ADC driver, and a precision 18-bit SAR ADC.
