MAX11902 ตัวแปลงอนาล็อกเป็นดิจิตอล SAR ใช้พลังไฟต่ำ ดิฟเฟอเรนเชี่ยลเต็มระบบ

Maxim's MAX11902 Low-Power Fully Differential SAR ADC is an 18-bit, 1Msps, single-channel, fully differential SAR analog-to-digital converter 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 ±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 98.9dB SNR and -123dB THD, guarantees 18-bit resolution with no-missing codes and 1.5 LSB INL (max). The MAX11902 communicates data using a SPI compatible serial interface.
