Newly available from austriamicrosystems is an audio front-end device that achieves low power consumption with high audio performance by featuring a sub-7 mW stereo DAC at over 100 dB SNR (signal-to-noise ratio).
The AS3543 combines in a single chip all system analog functions required in a digital system-on-chip (SoC) for mobile entertainment products. It is a flexible and highly integrated audio and power management device which includes functions such as low power stereo audio DACs and ADCs with line audio output and input, microphone input, headphone amplifier with direct drive capabilities, battery charging for Li-Ion and other popular types, efficient DC-DC step-up/step-down power converters, LDOs, low power RTC, battery switch and high voltage backlight power unit. Advanced power management techniques like dynamic voltage with frequency scaling and adjustable DC-DC converters enable high efficiency over a wide range of current loads.
Handheld entertainment devices are increasingly docked in a cradle and connected to the speaker system of a car or home speaker accessory where the portable device replaces a traditional HiFi system. In both scenarios the AS3543 takes advantage of a unique feature to minimise the ground noise generated by the engine in the car or high current switching Class-D amplifier from the speakers dock; a typical 3 dB SNR gain has been measured at the reproducer by employing this technique.
