The AD7982 is an 18-bit, successive approximation, analog-to-digital converter (ADC) that operates from a single power supply, VDD. The AD7982 contains a low power, high speed, 18-bit sampling ADC and a versatile serial interface port. On the CNV rising edge, the AD7982 samples the voltage difference between the IN+ and IN− pins. The voltages on these pins usually swing in opposite phases between 0 V and VREF. The reference voltage, VREF, is applied externally and can be set independent of the supply voltage, VDD. Its power scales linearly with throughput.The serial peripheral interface (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. The AD7982 is compatible with 1.8 V, 2.5 V, 3 V, and 5 V logic, using the separate VIO supply.The AD7982 is available in a 10-lead MSOP or a 10-lead LFCSP with operation specified from −40°C to +85°C.
