An Improved Balanced, Floating Output Driver IC

Authors: Hebert, Gary K.

AES Convention 108 · Paper 5152 · February 2000

Abstract

The design and implementation of an improved balanced, floating output driver IC for professional audio applications is described. It is shown that when the most common existing designs are used to drive ground-referred loads, the grounded output is forced into current limiting whenever the active output clips. This results in large current spikes flowing into the ground of the receiving device. Techniques used to eliminate this problem as well as the overall performance of the resulting design are described.
