The Audio-Mojo is a development board for the QF1D512 SavFIReTM digital filter chip.It features analog audio inputs and outputs, an audio codec, two QF1D512s and a microcontroller to provide non-volatile storage of settings and automatic load and run at power up. This board allows the QF1D512 to be evaluated for numerous audio applications including equalizer and digital speaker crossovers. Two complete sttings are pre-programmed into the board to illustrate stereo equalizer and digital crossover functionality.
A demonstration platform featuring the Quickfilter QF1D512 in the prototype area of an ARM7TDMI platform – the Atmel AT91SAM7S256-EK Evaluation Board.The QF1D512 acts as a coprocessor to the ARM microcontroller, providing sophisticated filtering capability with no processor overhead, freeing the microcontroller for other system related tasks.
Demonstration platform for a digital microphone circuit featuring the Quickfilter QF1D512 in conjunction with a Texas Instruments MSP430 microcontroller and codec.The design features small size and extremely low power consumption.
