DESCRIPTION

The SGM56101Q is an 8-channel, 32-bit DAC designed for digital audio systems. Its internal circuitry boasts a state-of-the-art 32-bit digital filter that optimizes both audio quality and short group delay. With support for a maximum 192kHz PCM input, it is ideal for reproducing high-resolution audio sources that are increasingly common in network audios, USB-DACs and car audio systems.
Furthermore, the SGM56101Q incorporates the innovative OSR-doubler technology, enabling it to handle a diverse range of signals while minimizing out-of-band noise and maintaining low power consumption. Additionally, the device provides three types of 32-bit digital filters, which can enable sound making simple and flexible in wide range of applications. It should be noted that SGM56101Q needs to input the MCLK signal in advance to execute the 3-wire serial/I2C-bus program.
The device is AEC-Q100 qualified (Automotive Electronics Council (AEC) standard Q100 Grade 1) and it is suitable for automotive applications.
The SGM56101Q is available in a Green TQFN-5×5-32FL package.
