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/MAX1309/
MAX1310 provide a ±5V input range with ±16.5V fault-
tolerant 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.
• 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 provides
the conversion results and accepts digital inputs that acti-
vate each channel individually.
● ±1 LSB INL, ±0.9 LSB DNL (max)
● 84dBc SFDR, -86dBc THD, 71dB SINAD,
All devices operate from a +4.75V to +5.25V analog sup-
ply and a +2.7V to +5.25V digital supply and consume
57mA total supply current when fully operational.
