Atmel has released its AT73C209 Analog Companion power supply and audio interface IC designed for low-cost music players. It supplies the required voltages and currents to all the sections of these portable devices, taking energy from a single alkaline battery, and also provides a high-quality audio interface.
The module has two linear regulators (LDO) and one very low input voltage and highefficiency step-up switching regulator (DC-DC) working down to 0,9 V, thus particularly suited for 1-cell Alkaline/NiMh batteries. On the audio side, it offers an audio-quality 16-bit stereo audio DAC with headset driver and microphone preamplifier to interface with the recording stage of an MCU.
The AT73C209 is available in a 7 x 7 mm, 32-pin QFN package in order to satisfy portable device manufacturers’ minimum space requirements and low cost.
