MAX11902 EVALUATION KIT AVAILABLE 18-Bit, 1Msps, Low-Power, Fully Differential SAR ADC General Description The MAX11902 is an 18-bit, 1Msps, single-channel, fully differential SAR ADC with internal reference buffers. The MAX11902 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 98.9dB SNR and -123dB THD, guarantees 18-bit resolution with no-missing codes and 1.5 LSB INL (max). The MAX11902 communicates data using a SPIcompatible serial interface. The MAX11902 is offered in a 20-pin, 4mm x 4mm, TQFN package and is specified over the -40°C to +85°C* operating temperature range.
