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 CS 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.
