GENERAL DESCRIPTION

The AD7982BCPZ-RL7 is an 18-bit, successive approximation, analog-to-digital converter(ADC) that operates from a single power supply, VDD. It contains a low power, high speed,18-bit sampling ADC and a versatile serial interface port. On the CNV rising edge, the AD7982BCPZ-RL7 samples the voltage difference between the IN+and IN-pins. The voltages on these pins usually swing in opposite phases between 0 V and Vgr. 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,2.5V,3 V, and 5 V logic, using the separate VIO supply.
The AD7982BCPZ-RL7 is available in a 10-lead MSOP or a 10-lead QFN (LFCSP) with operation specified from-40℃ to+85℃.
