The MAX1304/ -5V to +5V (MAX1308/MAX1309/MAX1310) MAX1305/MAX1306 provide a 0 to +5V input range -10V to +10V (MAX1312/MAX1313/MAX1314) with 6V fault-tolerant inputs. The MAX1308/MAX1309/ MAX1310 provide a 5V input range with 16.5V fault- Fast Conversion Time One Channel in 0.72s tolerant inputs. The MAX1312/MAX1313/MAX1314 have Two Channels in 0.9s a 10V input range with 16.5V fault-tolerant inputs. Four Channels in 1.26s These ADCs convert two channels in 0.9s, and up to Eight Channels in 1.98s eight channels in 1.98s, with an 8-channel throughput of High Throughput 456ksps per channel. Other features include a 20MHz T/H 1075ksps/Channel for One Channel input bandwidth, internal clock, internal (+2.5V) or external 901ksps/Channel for Two Channels (+2.0V to +3.0V) reference, and power-saving modes. 680ksps/Channel for Four Channels A 20MHz, 12-bit, bidirectional parallel data bus provides 456ksps/Channel for Eight Channels the conversion results and accepts digital inputs that acti- 1 LSB INL, 0.9 LSB DNL (max) vate each channel individually. 84dBc SFDR, -86dBc THD, 71dB SINAD, All devices operate from a +4.75V to +5.25V analog sup- f = 500kHz at 0.4dBFS IN ply and a +2.7V to +5.25V digital supply and consume 12-Bit, 20MHz, Parallel Interface 57mA total supply current when fully operational.
