Detailed Description
The MAX1304–MAX1306/MAX1308–MAX1310/MAX1312–
MAX1314 are 12-bit ADCs. The devices offer 8, 4, or 2
independently selectable input channels, each with
dedicated T/H circuitry. Simultaneous sampling of all
active channels preserves relative phase information
making these devices ideal for motor control and power
monitoring. 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 conversion
results are available in 0.9μs. Conversion results from
all eight channels are available in 1.98μs. The 8-chan-
nel throughput is 456ksps per channel. Internal or
external 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 shutdown
feature reduces power. A 20MHz, 12-bit, parallel data
bus outputs the conversion results. Figure 2 shows the
functional diagram of these ADCs.
