... Low Power—The AD9214 at 285 mW consumes a fraction of the power available in existing high-speed monolithic solutions. In sleep mode, power is reduced to 30 mW. Single Supply—The AD9214 uses a single 3 V supply, simplify- ing system power supply design. It also features a separate digital output driver supply line to accommodate 2.5 V logic families. ...

... NOTES 1 Gain error and gain temperature coefficient are based on the ADC only (with a fixed 1.25 V external reference). 2 Measured with range for AD9214-80 and AD9214-105. Measured with REFSENSE externally connected to AGND, REF is configured as an output for the internal reference voltage. 4 REFSENSE externally connected REF is configured as an input for an external reference voltage ...

... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD9214 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... Special care was taken in the design of the analog input section of the AD9214 to prevent damage and corruption of data when the input is overdriven. The optimal input range is 1.0 V p-p, but the AD9214 can support a 2.0 V p-p input range with some degra- dation in performance (see DFS/GAIN pin description above). , the ADC is ...

... An example of this is shown in the evaluation board schematic in Figure 10. The series resistors should be placed as close to the AD9214 as possible to limit the amount of current that can flow into the output stage. These switching currents are confined between ground (DGND) and the DrV pins ...

... AD9214. Gain/Data Format The evaluation board is assembled with the DFS/GAIN pin connected to ground; this configures the AD9214 for p-p analog input range, and offset binary data format. The user may remove this jumper and replace it to make one of the connections described in the table below to configure the AD9214 for different gain and output data format options ...
