Dual-Channel VCAs: Methods for Powering Down One Channel
PDF, 102 Kb, File published: Jun 11, 2004
Texas Instruments offers several product groups of highly-integrated voltage-controlled amplifiers (VCAs) including the VCA2611/12/13/16 and the VCA2614/18/19. Both the VCA2611 and the VCA2614 families feature two channels, either of which can be powered while powering down the other. This application note outlines two possible approaches to this question and describes the steps needed to assure t
