The AD76861 is a 16-bit， charge redistribution， successive approximation， analog-to-digital converter （ADC） that operates from a single 5 V power supply， VDD. It contains a low power， high speed， 16-bit sampling ADC with no missing codes， an internal conversion clock， and a versatile serial interface port. The part also contains a low noise， wide bandwidth， short aperture delay track-and-hold circuit. On the CNV rising edge， the AD7686 samples an analog input IN+ between 0 V to REF with respect to a ground sense IN−。 The reference voltage， REF， is applied externally and can be set up to the supply voltage. Power dissipation scales linearly with throughput. The SPI-compatible serial interface also features the ability， using the SDI input， to daisy-chain several ADCs on a single， 3-wire bus or provides an optional busy indicator. This device is compatible with 1.8 V， 2.5 V， 3 V， or 5 V logic， using the separate supply VIO. The AD7686 is housed in a 10-lead MSOP or a 10-lead LFCSP with operation specified from −40°C to +85°C.
