The AD7999 is an I²C programmable resolution quad-channel analog to digital converter, capable of processing 22,500 samples per second.

The AD7999 supports communication speeds as high as 3.4MHz (requires a master capable of clock stretching above 1.7MHz). An internal tack and hold amplifier allows the AD7999 to measure analog voltage at frequencies as high as 14MHz.

The AD7999 uses a 5V reference voltage for all 4 input channels; however, the last channel may be sacrificed to serve as an external reference voltage input. The AD7999 has a fixed I²C address of 0x29, allowing one device per I²C port.

All I²C Mini Modules are designed to operate at 5VDC. Using a convenient 4-Pin plug, devices can be daisy-chained onto the I²C Bus, eliminating the need for soldering. Simply plug together the devices you need for your next automation application.

Pull-up resistors are included with all ControlEverything.com master devices. If you are wiring in your own I²C port, on-board 4.7K jumper-selectable pull-up resistors are available for convenience purposes.
