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 AD5934.
3 The peak-to-peak value of the ac output excitation voltage scales with supply voltage according to the following formula. VDD is the supply voltage.
Output Excitation Voltage (V p-p) = [2/3.3] × VDD
4 The dc bias value of the output excitation voltage scales with supply voltage according to the following formula. VDD is the supply voltage.
Output Excitation Voltage (V p-p) = [2/3.3] × VDD
5 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.
6 The accumulation of the currents into Pin 8, Pin 15, and Pin 16.
