Quad 12-bit analog-to-digital converter integrates four ADC cores with a high speed serial output interface. The converter supports 170 MSPS, 210 MSPS, and 250 MSPS operation from a 1.8 V supply and provides a 780 MHz full-power analog input bandwidth. Serialized packet outputs include channel-specific information, coded samples, and error correction code, with SPI-controlled power-down, test pattern, header, and pin-function features. The device is specified for −40 °C to +85 °C operation in a Pb-free, RoHS-compliant 72-lead LFCSP package.
