The MAX1316/ On-Chip T/H Circuit for Each Channel MAX1317/MAX1318 have a 0 to +5V input range with 10ns Aperture Delay 6.0V fault-tolerant inputs. The MAX1320/MAX1321/ 50ps Channel-to-Channel T/H Matching MAX1322 have a 5V input range with 16.5V fault-toler- Fast Conversion Time ant inputs. The MAX1324/MAX1325/MAX1326 have a One Channel in 1.6s 10V input range with 16.5V fault-tolerant inputs. These Two Channels in 1.9s ADCs convert two channels in 2s, and up to eight chan- Four Channels in 2.5s nels in 3.8s, and have an 8-channel throughput of 250ksps per channel.
