AK7735EQ Description

Short technical summary and product information.

The AK7735EQ is a highly integrated digital signal processor from Asahi Kasei Microdevices (AKM). It includes a 24-bit stereo ADC with MIC gain amplifiers, a 24-bit stereo ADC with input selector, two 32-bit stereo DACs, and two stereo sampling rate converters supporting sampling frequencies up to 192kHz. The device features dual DSP cores (DSP1 and DSP2) with shared memory, each offering 3072 step/fs parallel processing power at fs=48kHz.

 

The ADC section provides a signal-to-noise ratio of 106dB (typical at fs=48kHz, differential input, MIC gain=0dB), while the DAC section achieves a typical SNR of 108dB. The device supports I²C and SPI data interfaces, with SPI up to 6MHz and I²C up to 1MHz Fast Mode Plus. The AK7735EQ is a RAM-based DSP, freely programmable for user requirements such as acoustic effects and hands-free functions.

 

The AK7735EQ is available in a 48-pin LQFP package (7x7mm) for surface mount assembly. It is designed for audio processing applications requiring high-performance analog-to-digital and digital-to-analog conversion combined with powerful digital signal processing.
