Mosfet load board

16 07 2011

Three mosfets in parallel provide an adjustable load. Current is sensed with low side resistor. Reference is provided externally (DAC or pot).
Input voltage and current are fed into a PGA which is sent off board.
There is also an 8-bit i2c i/o expander and 18-bit i2c ADC available.

We’ve got your boards. The small interconnect boards are ours. Do you have a schematic of this board?

Nice, I used them on some ribbon cable where I needed to insert series resistance.

I’ve added a PDF schematic to the post.
