Комментарии об отличиях

ADS7946 ↔ RS1473

ADS7946: 14-bit, 2MSPS, dual-channel, unipolar, pseudo-differential SAR ADC, 2.7-5.25V supply, SNR 82dB, power 10.5mW, QFN16 3x3. RS1473: QFN3X3-16, pin-to-pin. Отличия: ADS7946 имеет auto power-down: 7.2mW@500kSPS, 1.4mW@100kSPS. Проверить: аналогичное поведение power-down у RS1473, channel-to-channel crosstalk (-95dB typ у ADS7946), INL/DNL (INL ±1.5 LSB max). Reference input impedance и settling time критичны для точности.
