Simultaneous-Sampling ADCsPin Description (continued)

The MAX1304–MAX1306/MAX1308–MAX1310/MAX1312–MAX1314 are 12-bit ADCs. The devices offer 8, 4, or 2independently selectable input channels, each withdedicated T/H circuitry. Simultaneous sampling of allactive channels preserves relative phase informationmaking these devices ideal for motor control and powermonitoring. Three input ranges are available, 0 to +5V,±5V and ±10V. The 0 to +5V devices provide ±6V fault-tolerant inputs. The ±5V and ±10V devices provide±16.5V fault-tolerant inputs. Two-channel conversionresults are available in 0.9µs. Conversion results fromall eight channels are available in 1.98µs. The 8-chan-nel throughput is 456ksps per channel. Internal orexternal reference and clock capability offer great flexi-bility, and ease of use. A write-only configuration regis-ter can mask out unused channels and a shutdownfeature reduces power. A 20MHz, 12-bit, parallel databus outputs the conversion results. Figure 2 shows thefunctional diagram of these ADCs.
