The S3ADSIQ80M12BSM40LL is an ultra low-power 12-bit dual-channel high-speed SAR ADC IP with a dual channel sampling frequency up to 80MS/s per channel. For maximum application flexibility, the power dissipation of this ADC scales with the sampling rate.
This 12-bit ADC can be used in single-channel mode or dual-channel mode allowing for I/Q operation. It features an excellent cross-channel performance that includes 0.1dB gain mismatch and -83dB crosstalk between channels.
Considering a dual-channel operation at sampling rate of 80MS/s per channel, a 10.7MHz input frequency and an input range of 1Vppdiff, this ADC IP features an outstanding dynamic performance that includes 83.8dB SFDR, -81.4dB THD, 64.2dB SNR and 10.4-bit ENOB.
This high-end performance is obtained while dissipating a mere 10.5mW for the complete ADC solution including internal reference voltage generation. That corresponds to an ultra efficient figure of merit of only 49fJ per converted sample per channel.
