MAX11905
20-Bit, 1.6Msps, Low-Power, Fully Differential SAR ADC
General Description
The MAX11905 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 ±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 98.3dB SNR and -123dB THD, guarantees 20-bit resolution with no-missing codes and 6 LSB INL (max). The MAX11905 communicates data using a SPIcompatible serial interface. The MAX11905 is offered in a 20-pin, 4mm x 4mm, TQFN package and is specified over the -40°C to +85°C operating temperature range.
