Analog Devices MAX11156 18-bit, 500ksps SAR ADC is a small true bipolar +/-5V, 18-bit analog-to-digital converter. MAX11156 offers excellent AC and DC performance with true bipolar input range, small size, and internal reference. The device measures a ±5V (10VP-P) input range while operating from a single 5V supply. A patented charge-pump architecture allows direct sampling of high-impedance sources. MAX11156 integrates an optional 6ppm/°C reference with internal buffer, saving the cost and space of an external reference. MAX11156 produces 94.6dB SNR and -105dB THD (typ).
