NOTES
1For applications in which +V
S 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.”
2To achieve guaranteed conversion rate, connect each data output to ground through a 2 k
Ω pull-down resistor.
3SNR 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.
4Crosstalk 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.
5Applies to both A/Ss and includes internal ladder dissipation.
Specifications subject to change without notice.
