1 _{Temperature range for Y version = −40°C to +125°C, typical at 25°C.}
2 _{The lower limit of the output excitation frequency can be lowered by scaling the clock supplied to the AD5933.}
3 _{Refer to Figure 14, Figure 15, and Figure 16 for the internal oscillator frequency distribution with temperature.}
4 _{The peak-to-peak value of the ac output excitation voltage scales with supply voltage according to the following formula:}
Output Excitation Voltage (V p-p) = [2/3.3] × VDD
where VDD is the supply voltage.
5 _{The dc bias value of the output excitation voltage scales with supply voltage according to the following formula:}
Output Excitation Bias Voltage (V) = [2/3.3] × VDD
where VDD is the supply voltage.
6 _{Guaranteed by design or characterization, not production tested. Input capacitance at the VOUT pin is equal to pin capacitance divided by open-loop gain of current-}
to-voltage amplifier.
7 _{The accumulation of the currents into Pin 8, Pin 15, and Pin 16.}
