The MAX1304–MAX1306/MAX1308–MAX1310/MAX1312–
MAX1314 are ideally suited for motor-control systems
(Figure 15). The devices’ simultaneously sampled
inputs eliminate the need for complicated DSP algo-
rithms that realign sequentially sampled data into a
simultaneous sample set. Additionally, the variety of
input voltage ranges allows for flexibility when choosing
current sensors and position encoders.
