MAX11905 Single-Channel ADC

Analog Devices Inc. MAX11905 Single-Channel Analog-to-Digital Converter (ADC) is a 20-bit, 1.6Msps, single channel, fully differential SAR ADC with internal reference buffers. The MAX11905 provides excellent static and dynamic performance with best-in-class power consumption that directly scales with throughput. The device has a unipolar differential ±V_REF 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 98.3dB SNR and -123dB THD, guarantees 20-bit resolution with no-missing codes, and 6 LSB INL (max). The MAX11905 communicates data using an SPI-compatible serial interface.
