Linear Technology LTC2345-18

the LTC2345-18 analog inputs allow the ADC to directly digitize a variety of signals, simplifying signal chain design. This input signal flexibility, combined with ±5LSB INL, no missing codes at 18 bits, and 91.8dB SNR, makes the LTC2345-18 an ideal choice for many applications requiring wide dynamic range. The LTC2345-18 supports pin-selectable SPI CMOS (1.8V to 5V) and LVDS serial interfaces.
