The AD79801 is a 16-bit, successive approximaTIon, analog-todigital converter (ADC) that operates from a single power supply, VDD. It contains a low power, high speed, 16-bit sampling ADC and a versaTIle serial interface port. On the CNV rising edge, it 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 independent of the supply voltage, VDD. Its power 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 and provides an opTIonal busy indicator. It is compatible with 1.8 V, 2.5 V, 3 V, or 5 V logic, using the separate supply VIO. The AD7980 is housed in a 10-lead MSOP or a 10-lead LFCSP with operation specified from −40°C to +125°C.
