General Description
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 0.9s, and up to eight
channels in 1.98s, 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.
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.
Each device is available in a 48-pin 7mm x 7mm LQFP
package and operates over the extended -40°C to
+85°C temperature range.
