Preventing Excess Power Consumption on Analog Switches
PDF, 238 Kb, File published: Jul 3, 2008
Analog switches are extensively used for switching audio signals in battery-powered applications, such as mobile phones. In any cases, the switch is powered directly from the battery, but it receives control signals from a lower voltage processor GPIO. For most analog switches, this application condition leads to an excess supply current draw that catches system designers by surprise. This applica
