... Out of Range (OTR)—The OTR output bit indicates when the input signal is beyond the AD9244’s input range. Single Supply—The AD9244 uses a single +5V power sup- ply simplifying system power supply design. It also features a separate digital output driver supply line to accommodate 3V and 5V logic families ...

... The clock period may be extended with no degradation in specified performance at +25°C. 2 For the AD9244-65 only, with duty cycle stabilizer enabled. DCS function not applicable for -40 model. 3 Output delay is measured from clock 50% transition to data 50% transition, with 5pF load on each output. 4 Wake-up time is dependent on value of decoupling capacitors, typical values shown with 0.1 F and 10 F capacitors on REFT and REFB. ...

... 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 AD9244 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recom- mended to avoid performance degradation or loss of functionality ...

... This latency is not a concern in many applications. The digital output, together with the out-of- range indicator (OTR), is latched into an output buffer to drive the output pins. The output drivers of the AD9244 can be configured to interface with +5V or +3V logic families. Connecting the DUTY pin to AVDD implements the internal clock stabilization function in the AD9244 ...

... PRELIMINARY TECHNICAL DATA For noise sensitive applications, the very high bandwidth of the AD9244 may be detrimental and the addition of a series resistor and/or shunt capacitor can help limit the wideband noise at the ADC’s input by forming a low pass filter. The source impedance driving VIN+ and VIN- should be matched ...

... USING THE INTERNAL REFERENCE The AD9244 can be easily configured for either a 1V p-p differential input span or 2V p-p input span by setting the internal reference. Other input spans can be realized with two external gain-setting resistors as shown in Figure 6 of this data sheet, or using an external reference ...
