GENERAL DESCRIPTION

circuit. On the

falling edge, it samples the voltage difference

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

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 package, with an

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