D –2– AD9002–SPECIFICATIONS NOTES 1Measured with AIN = 0 V. 2Measured by FFT analysis where fundamental is –3 dBc. 3Input slew rate derived from rise time (10 to 90%) of full scale input. 40utputs terminated through 100 Ω to –2 V. 5Measured from ENCODE in to data out for LSB only. 6For full-scale step input, 8-bit accuracy is attained in specified time. 7Recovers to 8-bit accuracy in specified time after 150% full-scale input overvoltage. 8Output time skew includes high-to-low and low-to-high transitions as well as bit-to-bit time skew differences. 9ENCODE signal rise/fall times should be less than 10 ns for normal operation. 10Measured at 125 MSPS encode rate. 11Analog input frequency = 1.23 MHz. 12RMS signal to rms noise, with 1.23 MHz analog input signal. 13Input signals 1 V p-p @ 1.23 MHz and 1 V p-p @ 2.30 MHz. 14Supplies should remain stable within ± 5% for normal operation. 15Measured at –5.2 V ± 5%.
