Product Brief DA9057
Eight analogue input pins allow multiple audio
sources to be internally mixed, eliminating the need
for external switches. Both single-ended and fully-
differential line and microphone inputs are supported
with built-in variable gain amplifiers to optimize
dynamic range prior to digitisation. This allows a
diverse variety of analogue audio sources such as
baseband voice, mobile TV, WiFi and FM radio to be
managed.
Input and output mixers with stereo-to- mono
conversion also support mono configurations such
headset/baseband line outputs. In addition to the fully
differential mono RX channel, two volume-controlled
differential/single-ended stereo line out drivers and
ground centered stereo amplifiers will directly drive
standard 3-wire 16ohm headphones.
PMIC Features
Switched DC/USB Charger with power path management
4 Buck Converters (3 with DVS) 0.5V-3.6V up to 1Amp
10 Programmable LDO’s High PSRR, 1% accuracy.
Low power Backup Charger 1.1-3.1V up to 6mA
32kHz RTC Oscillator
10 channel general Purpose ADC with touch screen
interface
High voltage White LED driver 24V/ 50mA Boost, 3 strings
16 bit GPIO bus for enhanced wakeup and peripheral
control
Dual serial control interfaces
Unique USB supply detection and charge current selection
Unique ID code capability with OTP memory
For example the dc-coupled, dedicated pop-free
drivers may be connected to stereo headphones,
stereo speaker and mono line out, all simultaneously
and without external switches.
All filtering and sidetone functions are performed
digitally including 5-band EQ and a digital input AGC
with programmable attack and decay parameters.
A configurable signal processing filter engine allows
various audio application enhancements and effects
i.e. acoustic filtering, wind noise suppression and 3D
sound.
Alternatively the filter engine may be programmed to
improve the frequency response of an external
speaker or headphone by providing an 8-pole per
channel equalisation function. This is available in
