The programmable input SAR analog-to-digital converter provides 14-bit resolution at up to 1 MSPS in warp mode. It supports unipolar and bipolar input ranges of 0 V to 5 V, 0 V to 10 V, ±5 V, and ±10 V. The device includes an internal 5 V reference and supports parallel 14-bit or 8-bit bus operation as well as a serial SPI-compatible interface. Operation is specified from −40°C to +85°C, with 48-lead LQFP and 48-lead LFCSP package options.
