描述 Description

The STA321MP is a PDM high-performance multichannel processor with ultra-low quiescent current designed for general-purpose digital microphone applications. The device is fully digital and is comprised of three main sections. The first section is the PDM input interface which can

accept up to six serial digital inputs. The second section is a high-quality audio processor allowing

flexible channel mixing/muxing and provides up to 10 biquads for general sound equalization and

voice enhancement with independent volume control.
