19-3052; Rev 3; 8/04
8-/4-/2-Channel, 12-Bit, Simultaneous-Sampling ADCs
with ±10ꢀ, ±±ꢀ, and 0 to +±ꢀ Analog Input Ranges
General Description
Features
♦ Up to Eight Channels of Simultaneous Sampling
8ns Aperture Delay
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/MAX130ꢀ/
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.ꢀµs, and up to eight
channels in 1.ꢀ8µs, 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.
100ps Channel-to-Channel T/H Match
♦ Extended Input Ranges
0 to +5V (MAX1304/MAX1305/MAX1306)
-5V to +5V (MAX1308/MAX1309/MAX1310)
-10V to +10V (MAX1312/MAX1313/MAX1314)
♦ Fast Conversion Time
One Channel in 0.72µs
Two Channels in 0.9µs
Four Channels in 1.26µs
Eight Channels in 1.98µs
♦ 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.
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.
