8-/4-/2-Channel,with ±10V, ±5V12-Bit,, and 0 to +5V Analog Input Ranges

Simultaneous-Sampling ADCsGeneral Description

The MAX1304–MAX1306/MAX1308–MAX1310/MAX1312– Up to Eight Channels of Simultaneous Sampling

MAX1314 12-bit, analog-to-digital converters (ADCs) offereight, four, or two independent input channels.8ns Aperture Delay

Independent track-and-hold (T/H) circuitry provides simul-100ps Channel-to-Channel T/H Matchtaneous sampling for each channel. The MAX1304/ Extended Input Ranges

MAX1305/MAX1306 provide a 0 to +5V input range with0 to +5V (MAX1304/MAX1305/MAX1306)±6V fault-tolerant inputs. The MAX1308/MAX1309/-5V to +5V (MAX1308/MAX1309/MAX1310)MAX1310 provide a ±5V input range with ±16.5V fault-tol--10V to +10V (MAX1312/MAX1313/MAX1314)erant inputs. The MAX1312/MAX1313/MAX1314 have a Fast Conversion Time

±10V input range with ±16.5V fault-tolerant inputs. TheseADCs convert two channels in 0.9µs, and up to eightOne Channel in 0.72µschannels in 1.98µs, with an 8-channel throughput ofTwo Channels in 0.9µs456ksps per channel. Other features include a 20MHz T/HFour Channels in 1.26µsinput bandwidth, internal clock, internal (+2.5V) or externalEight Channels in 1.98µs
