Additional Infomation About Product

STA321MP Scalable digital microphone processor Datasheet - production data Description The STA321MP is a PDM, high-performance, multichannel processor with ultra-low quiescent 74)3 current. It is designed for general-purpose digital PP PP microphone applications. The device is fully digital and is comprised of three main sections. The first section is the PDM input interface which Features can accept up to six serial digital inputs. The second section is a high-quality audio processor 8 digital processing channels each 24-bits allowing flexible channel mixing/muxing and 6 channels of PDM input provides up to 10 biquads for general sound 2 additional virtual channels equalization and voice enhancement with independent volume control. The last block is the >100 dB SNR and dynamic range IS output interface which streams out the Digital gain/attenuation 58 dB to -100 dB in processed digital audio. The output interface can 0.5 dB steps also be programmed for flexible channel Soft volume update mapping. The device offers some of the most commonly required audio enhancements such as Individual channel and master level control programmable voice tuning and equalization, Up to 10 independent 32-bit user- limiter/compressor for improved voice quality, programmable biquads (EQ) per channel multiband selection for customizable microphone Bass/treble tone control usage, and configurable wind-noise rejection. The embedded digital processor allows the Pre- and post-EQ full 8-channel input mix on all microphone processing to be offloaded from the 8 channels main CPU or SoC to the device. Dual independent limiters/compressors Dynamic range compression or anti-clipping Table 1.
