This is a dual feedback-loop design that prevents the

excessive ground currents typical of cross-coupled

output stages (CCOS) when clipping into sin-

gle-ended loads. OutSmarts uses two individual neg-

currents, making the designs inherently more stable

and less sensitive to component tolerances than

common CCOSes. As a result, THAT's topology pre-

vents the loss of common-mode feedback that

plagues common CCOS designs when clipping into

single-ended loads. This avoids excessive ground

currents that would otherwise upset power supplies

and create additional distortion, even in adjacent

channels.

and DRV135, as well as the Analog Devices

SSM2142. The 1606 offers an advanced com-

mon-mode offset voltage reduction scheme, which re-

quires a small single capacitor instead of the two

electrolytics

pin-compatible cousins. Additionally, the 1606 fea-

tures differential inputs in a space-saving 16-pin

QSOP package. Both parts offer +6 dB gain.
