AD9022 load is a single LS latch.
RMS signal-to-rms noise with analog input signal 1 dB below full scale at specified frequency. Tested at 55% duty cycle.
Intermodulation measured with analog input frequencies of 8.9 MHz and 9.8 MHz at 7 dB below full scale.
PSRR is sensitivity of offset error to power supply variations within the 5% limits shown.
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.
