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  
CS  
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.
