The 16-bit Sigma-Delta ADC supports a sampling rate of 16KSPS and is crafted using 55nm 2P7M SMIC CMOS technology. Notably, it offers programmable gain settings from 0 to 50 dB, providing flexibility in adjusting to varying signal strengths. The ADC supports both PDM (Pulse Density Modulation), I2S, and TDM (Time-Division Multiplexing) interfaces, making it adaptable for various audio processing applications.
This converter is designed to handle mono audio inputs effectively, operating over a digital range that spans from AVSS to AVDD, which ensures a broad compatibility with diverse audio equipment. It maintains a high signal-to-noise ratio (SNR) of 90dB, critical for high-fidelity audio processing requirements, and features low current consumption figures, both in active and power-down states, enhancing energy efficiency.
Applications for this ADC extend into digitally-intensive audio environments, including microphones and high-resolution audio streaming devices. Its technology and features make it a go-to choice for systems requiring precision audio digitization under power constraints, such as in portable and battery-dependent audio equipment.
