Features +\/-4.096 V differential input, internal 4.096 V reference with 2.5 ppm\/C drift, +\/-1.0 LSB INL, and 91.5 dB SNR. Consumes only 80 mW at 1 MSPS. No pipeline delay from SAR architecture. Operates from 5 V analog and 2.5-5.25 V digital supply.","working_principle":"The AD7671 uses a charge-redistribution SAR architecture. (1) Sample\/Hold: Input sampling switch connects differential input to capacitor array during acquisition. (2) SAR Conversion: 16-bit conversion proceeds MSB to LSB over 16 clock cycles. Internal DAC generates test voltage; comparator determines bit decision. (3) Internal Reference: 4.096 V bandgap reference with 2.5 ppm\/C drift. (4) Digital Interface: Serial (SPI\/QSPI\/MICROWIRE) or parallel interface for flexible processor connection.","pin_description":"
