MD3902/3905/3910
2/5/10MHz V/F Converters
OFFSET AND GAIN CALIBRATION
OFFSET CALIBRATION – Offset calibration
should be performed prior to gain calibration.
With a -10mV analog input signal at pin 11 of
the MD39XX, adjust the Offset potentiometer
until a frequency of 2.000/5.000/10.000kHz is
observed on output pins 21, 23 or 24.
GAIN CALIBRATION – With a full scale
analog input voltage of -10.00V on pin 11,
adjust the Gain potentiometer until a full-scale
frequency of 2.000/5.000/10.000MHz is
observed on output pin 21, 23 or 24.
N/C PINS – Pins marked as No Connect have no
electrical connection to the internal circuitry of
the MD39XX.
OUTPUT PINS – Pins 23 and 24 are tied together
internally. Either or both may be used as the
source of the frequency output of the MD39XX,
as long as the load specifications are not
exceeded. Pin 21 provides a complementary
signal relative to pins 23 and 24 with similar
loading limits.
