The new AS3658 from austriamicrosystems is a highly integrated power and audio management unit with sophisticated audio features.
It is ideally suitable for portable navigation devices, portable media players, smartphones, PDAs and a wide range of other battery powered handheld devices.
The chip offers an integrated solution for power supply generation, monitoring and battery management including charging. The charger can manage up to 1,6 A charging current, suitable for fast charging of large batteries. USB, linear and step-down charging is available and supported by the battery isolation feature. The programmable power management functions of the AS3658 help to extend battery life with DC/DC efficiencies higher than 90%. The IC provides three highly efficient DC/DC step-down converters, two DC/DC step-up converters, three low noise LDOs suitable for RF applications, four digital LDOs, a low noise charge pump and a highly flexible backlight driver supporting a wide range of display sizes.
The AS3658 also offers high performance audio functions with an 18-bit audio DAC, a 16-bit audio ADC, a 5-band equaliser as well as headphone amplifiers, line-outputs, line-inputs, microphone inputs, audio mixer and several analog and digital audio interfaces. The unique ground noise cancellation feature delivers excellent sound quality for in-car environments.
Moreover, a realtime clock, 10-bit general purpose ADC and a touch screen interface are integrated to complete the device's extensive feature set. Due to customisable PROM programmable startup sequences the IC matches a wide variety of application processors.
The AS3658 is available in a BGA124, 8 x 8 mm, 0,5 mm pitch package and is specified for -40 to +85&C ambient temperature.
