Maxim Integrated MAX1316ECM

Description
The MAX1316-MAX1318/MAX1320-MAX1322/MAX1324-MAX1326 are 14-bit analog-to-digital converters (ADCs) with two, four, or eight independent input channels. Each channel has independent track/hold (T/H) circuitry for simultaneous sampling. 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 2us, 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. They come in a 48-pin LQFP package and operate over the extended -40°C to 85°C temperature range.
