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 TQFP package and oper-

ate over the extended -40°C to +85°C temperature range.
