The NCP571 , NCV571 are low current voltage regulators available in few standard output voltage versions ( 0.8 V, 0.9 V, 1.0 V and 1.2 V ) . The NCP571 , NCV571 low dropout linear regulators are designed for handheld communication equipment and portable battery powered applications which require low quiescent current.
The SSM2380 is a fully integrated, high efficiency, stereo Class-D audio amplifier designed for mobile phone applications , mp3 players and other audio applications that require low output power . This class D audio amplifier circuit requires few external components and operates from a single 2.5 V to 5.5 V supply.
The LTC2259-16 is a ultralow power sampling 16-bit A/D converter designed for digitizing high frequency, wide dynamic range signals.
The LTC2259-16 require a low voltage power supply of 1.8 volts and has a very low power consumption of 89 miliwatts , that make it suitable for demanding communications applications with AC performance that includes 73.1dB SNR and 88dB spurious free dynamic range (SFDR).
The digital outputs of the ADC can be either full-rate CMOS, doubledata rate CMOS, or double-data rate LVDS.
