优势

To allow for application flexibility whilst offering minimum area and power dissipation, this IP does not include the Digital Decimation Filter. If required, it can be included in the IP or it can, otherwise, be included externally in the SoC DSP.
Excluding the Digital Decimation filter, this ADC power dissipation is only 2.0mW and occupies only 0.04mm2 area.
The S3ADSD40M14BT28 does not require any special analog process options.
