8-/4-/2-Channel, 14-Bit, Simultaneous-Sampling ADCs
with ±10V, ±5V, and 0 to +5V Analog Input Ranges
General Description
The MAX1316–MAX1318/MAX1320–MAX1322/MAX1324–
MAX1326 14-bit, analog-to-digital converters (ADCs) offer
two, four, or eight independent input channels.
Independent track/hold (T/H) circuitry provides simultane-
ous sampling for each channel. The MAX1316/
MAX1317/MAX1318 have a 0 to +5V input range with
±6.0V fault-tolerant inputs. The MAX1320/MAX1321/
MAX1322 have a ±5V input range with ±16.5V fault-toler-
ant inputs. The MAX1324/MAX1325/MAX1326 have a
±10V input range with ±16.5V fault-tolerant inputs. These
ADCs convert two channels in 2µs, and up to eight chan-
nels in 3.8µs, and have an 8-channel throughput of
250ksps per channel. Other features include a 10MHz
T/H input bandwidth, internal clock, internal (+2.5V) or
external (+2.0V to +3.0V) reference, and power-
saving modes.
A 16.6MHz, 14-bit, bidirectional, parallel interface pro-
vides the conversion results and accepts digital config-
uration inputs.
These devices operate from a +4.75V to +5.25V analog
supply and a separate +2.7V to +5.25V digital supply,
and consume less than 50mA total supply current.
These devices come in a 48-pin LQFP package and oper-
ate over the extended -40°C to +85°C temperature range.
