产品概述

描述

The STA321MPL1 is a PDM, high-performance, multichannel processor with ultra-low quiescent current. It is 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. The last block is the I²S output interface which streams out the processed digital audio. The output interface can also be programmed for flexible channel mapping. The device offers some of the most commonly required audio enhancements such as programmable voice tuning and equalization, limiter/compressor for improved voice quality, multiband selection for customizable microphone usage, and configurable wind-noise rejection. The embedded digital processor allows the microphone processing to be offloaded from the main CPU or SoC to the device. The STA321MPL1 has six digital microphone inputs, providing connections for up to three dual-membrane microphones.
