Description
DFM
Digital frequency signal output
DFM uses pulse voltage as an output monitoring signal;
Duty-cycle: 50%
Min. load impedance R
L
: 1 kΩ / 100 pF
Max. current endurance: 30 mA
Max. voltage: 30 V
DC
± 1 %
(when 30 V
DC
/ 30 mA / RL=100 pF)
Max. output frequency: 33 kHz
Current-limiting resistor R: ≥ 1 KΩ
Output load impedance R
L
Capacitive load ≤ 100 pF
Resistive load ≥ 1 kΩ, resistance determines the output
voltage value.
DFM-DCM voltage = external voltage × (R
L
÷ (R
