.. 19-3157; Rev 2; 8/04 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 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 powersaving 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 50m A total supply current. These devices e in a 48-pin TQFP package and operate over the extended -40°C to +85°C temperature range.
