The 18-bit charge redistribution SAR ADC converts fully differential analog inputs at up to 800 kSPS with no pipeline delay. It operates from a single 5 V analog and digital supply with a 2.7 V to 5.25 V output interface supply. The converter supports parallel 18-bit, 16-bit, or 8-bit bus operation and a serial interface compatible with SPI, QSPI, MICROWIRE, and DSP ports. Specified operation covers −40°C to +85°C in 48-lead LQFP and 48-lead LFCSP packages.
