AD9002–SPECIFICATIONS
NOTES
1
Measured with AIN = 0 V.
2
Measured by FFT analysis where fundamental is –3 dBc.
3
Input slew rate derived from rise time (10 to 90%) of full scale input.
4
0utputs terminated through 100
to –2 V.
5
Measured from ENCODE in to data out for LSB only.
6
For full-scale step input, 8-bit accuracy is attained in specified time.
7
Recovers to 8-bit accuracy in specified time after 150% full-scale input overvoltage.
8
Output time skew includes high-to-low and low-to-high transitions as well as
bit-to-bit time skew differences.
9
ENCODE signal rise/fall times should be less than 10 ns for normal operation.
10
Measured at 125 MSPS encode rate.
11
Analog input frequency = 1.23 MHz.
12
RMS signal to rms noise, with 1.23 MHz analog input signal.
13
Input signals 1 V p-p @ 1.23 MHz and 1 V p-p @ 2.30 MHz.
14
Supplies should remain stable within
±
5% for normal operation.
15
Measured at –5.2 V
±
5%.
