DESCRIPTION
Today’s consumers demand the best in audio/voice. They want crystal-clear sound wherever they
are in whatever format they want to use. APLUS delivers the technology to enhance a listener’s
audio/voice experience.
The aPR33A series are powerful audio processor along with high performance audio
analog-to-digital converters (ADCs) and digital-to-analog converters (DACs). The aPR33A series
are a fully integrated solution offering high performance and unparalleled integration with analog
input, digital processing and analog output functionality. The aPR33A series incorporates all the
functionality required to perform demanding audio/voice applications. High quality audio/voice
systems with lower bill-of-material costs can be implemented with the aPR33A series because of its
integrated analog data converters and full suite of quality-enhancing features such as sample-rate
convertor.
The aPR33A series C3.1 is Tape mode manages messages sequentially much like traditional
cassette tape recorders. Within tape mode two options exist, auto rewind and non-auto rewind.
Auto rewind mode configures the device to automatically rewind to the beginning of the message
immediately following recording or playback of the message. In tape mode, using either option,
messages must be recorded or played back sequentially, much like a traditional cassette tape
recorder specially designed for simple key trigger, user can record and playback the message.
Meanwhile, this mode provides the power-management system. Users can let the chip enter
power-down mode when unused. It can effectively reduce electric current consuming to 15uA and
increase the using time in any projects powered by batteries.
