MAX1304MAX1306/MAX1308MAX1310/MAX1312MAX1314 19-3052 Rev 5 3/11 8-/4-/2-Channel, 12-Bit, Simultaneous-Sampling ADCs with 10V, 5V, and 0 to +5V Analog Input Ranges General Description Features Up to Eight Channels of Simultaneous Sampling The MAX1304MAX1306/MAX1308MAX1310/MAX1312 8ns Aperture Delay MAX1314 12-bit, analog-to-digital converters (ADCs) offer 100ps Channel-to-Channel T/H Match eight, four, or two independent input channels. Independent track-and-hold (T/H) circuitry provides simul- Extended Input Ranges taneous sampling for each channel. The MAX1304/ 0 to +5V (MAX1304/MAX1305/MAX1306) -5V to +5V (MAX1308/MAX1309/MAX1310) MAX1305/MAX1306 provide a 0 to +5V input range with -10V to +10V (MAX1312/MAX1313/MAX1314) 6V fault-tolerant inputs. The MAX1308/MAX1309/ MAX1310 provide a 5V input range with 16.5V fault-tol- Fast Conversion Time One Channel in 0.72s erant inputs. The MAX1312/MAX1313/MAX1314 have a Two Channels in 0.9s 10V input range with 16.5V fault-tolerant inputs. These Four Channels in 1.26s ADCs convert two channels in 0.9s, and up to eight Eight Channels in 1.98s channels in 1.98s, with an 8-channel throughput of 456ksps per channel. Other features include a 20MHz T/H High Throughput 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 pro- 456ksps/Channel for Eight Channels vides the conversion results and accepts digital inputs 1 LSB INL, 0.9 LSB DNL (max) that activate each channel individually. 84dBc SFDR, -86dBc THD, 71dB SINAD, All devices operate from a +4.75V to +5.25V analog supply f = 500kHz at 0.4dBFS IN and a +2.7V to +5.25V digital supply and consume 57mA 12-Bit, 20MHz, Parallel Interface total supply current when fully operational.
