All three CFAs have a bias control section with a power-down command input. The shutdown function includes internal pull-up resistance to provide a default disable command, which when invoked, reduces power consumption to less than 100µA for an entire three-channel part. During ...
12 V to 5 V Converters LCD Bias Generators Peripherals and Add-On Cards Battery Backup Supplies Cellular Telephones Portable Instruments GENERAL DESCRIPTION The ADP1108 is a highly versatile micropower switch-mode dc-dc converter that operates from an input voltage supply as low as 2.0 V and typi...
Input coupling capacitors block any DC bias from the audio source and ensure maximum dynamic range. This typical connection diagram highlights the required external components and system level connections for proper operation of the device in popular use case. Any design variation can be supported by...
Internal current generator provides bias 7 FB current for loop regulation. A voltage below the threshold VFBbm activates the burst-mode operation. A level close to the threshold VFBlin means that we are approaching the cycle-by-cycle over-current set point. Brownout protection input with ...
These are high-voltage pins, with a threshold of 1.5 V for high level, and with direct connection directly to the battery for self-bias. The low threshold is 0.7 V. Both these pins have internal pullup currents of 0.5 µA (typical). As a result, an open circuit on these pins ...
