GENERAL DESCRIPTION

The AD7684 is a 16-bit, charge redistribution, successive

approximation, PulSAR® analog-to-digital converter (ADC)

that operates from a single power supply, VDD, between 2.7 V

to 5.5 V. It contains a low power, high speed, 16-bit sampling

ADC with no missing codes, an internal conversion clock, and a

serial, SPI-compatible interface port. The part also contains a low

noise, wide bandwidth, short aperture delay, track-and-hold circuit.

On the

falling edge, it samples the voltage difference

between +IN and –IN pins. The reference voltage, REF, is

applied externally and can be set up to the supply voltage. Its

power scales linearly with throughput.

The AD7684 is housed in an 8-lead MSOP, with an operating

temperature specified from −40°C to +85°C.
