8-/4-/2-Channel, 12-Bit, Simultaneous-Sampling ADCs
with ±10V, ±5V, and 0 to +5V Analog Input Ranges
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-

simultaneous sample set. Additionally, the variety of
input voltage ranges allows for flexibility when choosing
current sensors and position encoders.
