1. AGND1 and DGND1 are tied together at a single point near the DAC. Optimum placement for Rgnd was found by iteration while observing the
2. ICOMP1 and QCOMP1 MUST be tied together externally!
3. *E6 was mistakenly grounded so R56 should not be populated! E7, however, is correct and can be used to overdrive the internal reference op
