EK76 Evaluation Kit APPLICABLE PARTS (SOLD SEPARATELY) SA310KR INTRODUCTION This kit contains everything needed for rapid prototyping with the SA310KR 3-phase driver. With a multi- tude of circuit options, the EK76 offers versatility when in comes to connecting inputs, measuring outputs, and conditioning signals to the specific application environment. High- and low- input signals for each phase may be supplied from any 3 V to 18 V digital controller via standard pin header or SMA connectors. A remov- able 50 termination resistor is offered for impedance-matched inputs. Coaxial measurement points are offered for high-fidelity waveform measurement, so erroneous overshoot/ringing are cut down to a mini- mum. The layout is carefully optimized for signal and power transmission, while permitting easy integration with system controllers and 3-phase loads. ABSOLUTE MAXIMUM RATINGS All specifications listed in the SA310 datasheet apply to this board, except as noted below. This board uses components that limit SA310 s full operating range in exchange for convenience to the customer.
