Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
1 operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 6: The analog input is driven with a -0.4dBFS 500kHz sine wave.
Note 7: Shutdown current is measured with the analog input floating. The large amplitude of the maximum shutdown-current speci-
fication is due to automated test equipment limitations.
Note 8: CONVST must remain low for at least the acquisition period. The maximum acquisition time is limited by internal capacitor droop.
Note 9: CSto WRand CSto RDare internally AND together. Setup and hold times do not apply.
Note 10:Minimum CLK frequency is limited only by the internal T/H droop rate. Limit the time between the rising edge of CONVST
and the falling edge of EOLCto a maximum of 1ms.
