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.
2For applications in which +VS may be applied before –VS, or +VS current is not limited to 500 mA, a reverse biased clamping diode should be inserted between
ground and –VS to prevent destructive latch up. See section entitled “Using the AD9058.”
3Typical thermal impedances: 44-lead hermetic J-Leaded ceramic package: θJA = 86.4°C/W; θJC = 24.9°C/W; 48-lead hermetic DIP θJA = 40°C/W; θJC = 12°C/W.
4To achieve guaranteed conversion rate, connect each data output to ground through a 2 k Ω pull-down resistor.
5SNR performance limits for the 48-lead DIP “D” package are 1 dB less than shown. ENOB limits are degraded by 0.3 dB. SNR and ENOB measured with
analog input signal 1 dB below full scale at specified frequency.
6Crosstalk rejection measured with full-scale signals of different frequencies (2.3 MHz and 3.5 MHz) applied to each channel. With both signals synchronously
encoded at 40 MSPS, isolation of the undesired frequency is measured with an FFT.
7Applies to both A/Ss and includes internal ladder dissipation.
