3-Phase Motor Controller

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.
