8-/4-/2-Channel, 12-Bit, Simultaneous-Sampling ADCs  
with ±10, ±±, and 0 to +±ꢀ Analog Input Ranges  
680/2–MAX314  
General Description  
Features  
o Up to Eight Channels of Simultaneous Sampling  
The MAX1304–MAX1306/MAX1308–MAX1310/MAX1312–  
MAX1314 12-bit, analog-to-digital converters (ADCs) offer  
eight, four, or two independent input channels.  
Independent track-and-hold (T/H) circuitry provides simul-  
taneous sampling for each channel. The MAX1304/  
MAX1305/MAX1306 provide a 0 to +5V input range with  
6V fault-tolerant inputs. The MAX1308/MAX1309/  
MAX1310 provide a 5V input range with 16.5V fault-tol-  
erant inputs. The MAX1312/MAX1313/MAX1314 have a  
10V input range with 16.5V fault-tolerant inputs. These  
ADCs convert two channels in 0.9µs, and up to eight  
channels in 1.98µs, with an 8-channel throughput of  
456ksps per channel. Other features include a 20MHz T/H  
input bandwidth, internal clock, internal (+2.5V) or external  
(+2.0V to +3.0V) reference, and power-saving modes.  
8ns Aperture Delay  
100ps Channel-to-Channel T/H Match  
o Extended Input Ranges  
0 to +5V (MAX1304/MAX1305/MAX1306)  
-5V to +5V (MAX1308/MAX1309/MAX1310)  
-10V to +10V (MAX1312/MAX1313/MAX1314)  
o Fast Conversion Time  
One Channel in 0.72µs  
Two Channels in 0.9µs  
Four Channels in 1.26µs  
Eight Channels in 1.98µs  
o High Throughput  
1075ksps/Channel for One Channel  
901ksps/Channel for Two Channels  
680ksps/Channel for Four Channels  
456ksps/Channel for Eight Channels  
A 20MHz, 12-bit, bidirectional parallel data bus pro-  
vides the conversion results and accepts digital inputs  
that activate each channel individually.  
o
1 LSB INL, 0.9 LSB DNL (max)  
o 84dBc SFDR, -86dBc THD, 71dB SINAD,  
All devices operate from a +4.75V to +5.25V analog supply  
and a +2.7V to +5.25V digital supply and consume 57mA  
total supply current when fully operational.
