Linear Technology LTC2373-18

the LTC2373-18 has a highly configurable, low crosstalk 8-channel input multiplexer, supporting fully differential, pseudo-differential unipolar and pseudo-differential bipolar analog input ranges. The LTC2373-18 achieves ±2.75LSB INL (maximum) in all input ranges, no missing codes at 18-bits and 100dB (fully differential)/ 95dB (pseudo-differential) SNR (typical). The LTC2373-18 has an onboard low drift (20ppm/°C max) 2.048V temperature-compensated reference and a singleshot capable reference buffer.
