FDA001
Automotive class-D audio power DAC with
backlight LED driver and voice encoder
Features
■ FDA001 - dPal integrates:
– a LED driver with dimming capability
– an audio DAC converting a digital input into
an analog stereo signal
– a stereo headphone output
– a class-D amplifier with programmable
output power
– a configurable DSP for sound equalization
and volume/gain control
– a CODEC for microphone input
– a DC/DC converter that can be used to
step-down the car battery to supply the
portable device directly with car battery
with no need of CLA, or to step-up the input
USB voltage to have higher output power
■ Synchronous switching voltage pre-regulator:
– Internal high-side/low-side NDMOS
– Vout = 5/6/7/8 V selectable through I2C bus
– 3 A load current capability in step-down mode
– Out-of-regulation flag on dedicated
hardware pin
■ Step-up switching voltage regulator for 10
LEDs driving:
– Internal NDMOS switch
– LED current control through dedicated pin
– LED current selectable between 2.5 and
20 mA through I2C bus, allowing LED
luminosity dimming
■ Audio DSP and DAC with class-D power output
and class-AB stereo headset output:
–Pout = 6 W on 4 Ω load with pre-regulator
output set to 7 V
– 93 dB dynamic range output signal for
headset
– -60 dB<=>+12 dB volume control
selectable through I2C bus
– 5-bands equalizer
– signal dynamic compression
■ Voice CODEC for microphone input:
– 0/+20 dB pre-amplifier Gain, selectable
through I2C bus
– 0<=>22.5 dB amplifier gain, selectable
through I2C bus with 1.5 dB steps
■ Load dump protection
■ Thermal protection
■ Robustness against ESD events
Description
FDA001 - dPal (digital Portable Audio and Led
driver) is a very compact and complete
companion IC for portable navigation devices or
for advanced navigation head units.
It enhances the multimedia experience of
navigation sets by adding a powerful and clear
audio while allowing a very bright and uniform
display backlighting.
The automotive compatibility is ensured by the
integrated DC/DC converter which allows to
connect the IC directly to the car battery.
The same DC/DC boosts up the output audio
power when connected to USB supply.
It is designed in a proprietary advanced BCD
(Bipolar Cmos Dmos) silicon technology which
allows to integrate in one chip both high-speed
logic and power stages.
