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 simultaneous 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-tolerant 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 channels 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 provides the conversion results and accepts digital configuration 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 operate over the extended -40°C to +85°C temperature range.
