ADC128S022 8-Channel, 50 kSPS to 200 kSPS, 12-Bit A/D Converter August 2005 ADC128S022 8-Channel, 50 kSPS to 200 kSPS, 12-Bit A/D Converter General Description The ADC128S022 is a low-power, eight-channel CMOS 12bit analog-to-digital converter specified for conversion throughput rates of 50 kSPS to 200 kSPS. The converter is based on a successive-approximation register architecture with an internal track-and-hold circuit. It can be configured to accept up to eight input signals at inputs IN0 through IN7. The output serial data is straight binary and is compatible with several standards, such as SPI™, QSPI, MICROWIRE, and many common DSP serial interfaces. The ADC128S022 may be operated with independent analog and digital supplies. The analog supply (VA) can range f [ ... ]
