Description
Output of Operational Amplifier. The operational amplifier, along with C
is used in the integrate stage of the V to F conversion.
Positive Analog Input.
Negative Analog Input.
On-Chip Current Source. This can be used in conjunction with an external
resistor to remove the operational amplifier’s offset.
Negative Power Supply Input.
The Capacitor, C
for the one shot.
No Connect.
Frequency Output from AD650.
Input to Comparator. When the input voltage reaches −0.6 V, the one shot is
triggered.
Digital Ground.
Analog Ground.
Positive Power Supply Input.
Offset Null Pins. Using an external potentiometer, the offset of the
operational amplifier can be removed.
