no grounds in the signal path after the low-level signal at the transformer input. The two pull-down resistors do
show a signal path ground and should be connected at the same physical point to ground to eliminate
imbalanced ground return currents from degrading 2nd-harmonic distortion.

design-in tools
demonstration boards
Two PC boards are available to assist in the initial evaluation of circuit performance using the OPA4684 in its
two package styles. Both of these are available, free, as an unpopulated PC board delivered with descriptive
documentation. The summary information for these boards is shown in Table 1.
