Audio and Power subsystem for advanced
applications processors
The DA9034 is a complete and highly
integrated analog baseband solution.
Designed to support advanced
applications processors, the DA9034
provides all power management and
audio functions for advanced
handset/PDA/PNA designs.
Connecting directly to the battery the
DA9034 provides stable, low noise
supplies for all core voltage domains,
with additional regulators for supplying
peripheral ICs.
All supplies are fed using high
performance low dropout (LDO) voltage
regulators using Dialog’s patented Smart
Mirror ™ technology (patent pending)
offering very low quiescent current
consumption and high power supply
rejection performance. Smart Mirror ™
regulators remove the need for a low
power mode, simplifying power control.
Two high efficiency DC-DC buck
converters provide high current, low
voltage supplies to the processor core
and memory. The main converter
features Dynamic Voltage Management
(DVM) with programmable voltage and
slew rate control.
The DA9034 also provides a range of
other functions including battery charger,
touchscreen interface and programmable
LED drivers to enable a complete system
to be realized without requiring additional
external IC’s.
Complementing the power management
function is a full audio subsystem
containing a voice codec and HiFi stereo
DAC. The codec’s are supported by a
range of analog interfaces including
loudspeaker and headphone drivers.
Ancillary functions include programmable
white LED and general purpose LED
drivers, vibrator driver and support for
USB interfacing (VBUS generation
monitoring and control). Also included is
full time battery supervision with
over/under voltage, over current and
thermal protection.
