AD7980ARMZRL7

AD7980 is a 16-bit, successive approximation, analogue-to-digital converter (ADC). It 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 analogue input, IN+, between 0V 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 widely used in application such as automated test equipment, data acquisition systems, medical instruments, machine automation etc.
