The 16-bit charge-redistribution SAR analog-to-digital converter operates from a single 5 V supply and supports up to 1 MSPS throughput in Warp mode. Its unipolar analog input range is 0 V to 2.5 V, with an internal 2.5 V reference and no pipeline delay. The converter provides serial and parallel digital interfaces compatible with 3 V and 5 V logic, including SPI, QSPI, MICROWIRE, and DSP-compatible operation. Operation is specified from -40°C to +85°C, with 48-lead LQFP and 48-lead LFCSP package options.
