MAX11960 EVALUATION KIT AVAILABLE Dual Simultaneous Sampling, 20-Bit, 1Msps, Differential SAR ADC General Description The MAX11960 is a 20-bit, 1Msps, dual simultaneous sampling, fully differential SAR ADC with internal reference buffers. The MAX11960 provides excellent static and dynamic performance with best-in-class power consumption that directly scales with throughput. The device has a unipolar differential ±VREF input range. Supplies include a 3.3V supply for the reference buffers, a 1.8V analog supply, a 1.8V digital supply, and a 1.5V to 3.6V digital interface supply. This ADC achieves 99dB SNR and -123dB THD, guarantees 20-bit resolution with no-missing codes and 5 LSB INL (max). The MAX11960 communicates data using a SPIcompatible serial interface.
