We describe updates to our current driver design allowing for higher output currents, both positive and negative currents, and updated digital interfacing to the microcontroller. We also discuss measurement of the noise spectral density of the driver with a better technique, showing that the driver's actual current noise density is about an order of magnitude lower than the upper limit we previously determined.
