s Features
For the loading motor channel, there are 4 modes, that is, forward rotation, reverse rotation, brake and standby modes, and you can select a mode among them. The gain of it is fixed to 6 dB (±0.5 dB) with a small dispersion among the products. 3.3 V supply voltage is available due to an external
PNP-tr. Driver I/O gain setting is possible with an additional external resistor Since the output and input lines are separated and respectively collected together, pattern designing is relatively easy.
