NOTES
1AD9022 load is a single LS latch.
2RMS signal-to-rms noise with analog input signal 1 dB below full scale at specified frequency. Tested at 55% duty cycle.
3Intermodulation measured with analog input frequencies of 8.9 MHz and 9.8 MHz at 7 dB below full scale.
4PSRR is sensitivity of offset error to power supply variations within the 5% limits shown.
Specifications subject to change without notice.

NOTES
1Absolute maximum ratings are limiting values to be applied individually, and
beyond which the serviceability of the circuit may be impaired. Functional
operability is not necessarily implied. Exposure to absolute maximum rating
conditions for an extended period of time may affect device reliability.
2Typical thermal impedances: “Q” Package (Ceramic DIP): θJC = 10°C/W; θJA =
35°C/W. “Z” Package (Gullwing Surface Mount): θJC = 13°C/W; θJA = 45°C/W.
