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 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%.
Specifications subject to change without notice.
