The AD654JR is an integrated voltage-to-frequency converter (VFC) designed by Analog Devices. It typically comes in an 8-pin SOIC (Small Outline Integrated Circuit) package. Below are the pin functions for this version:
1. Pin 1 (NC): No connection.
2. Pin 2 (VIN): Input voltage pin; the voltage to be converted to frequency is applied here.
3. Pin 3 (GND): Ground pin; serves as the reference point for the input and output signals.
4. Pin 4 (V-): Negative supply voltage pin.
5. Pin 5 (COMP): Compensation pin; connected to an external capacitor for frequency stability.
6. Pin 6 (V+): Positive supply voltage pin.
7. Pin 7 (FOUT): Frequency output pin; provides the frequency signal corresponding to the input voltage.
8. Pin 8 (RSET): Resistor set pin; an external resistor connected here determines the scaling factor between input voltage and output frequency.
The AD654JR is widely used for applications requiring the conversion of analog signals to frequency signals, offering good linearity and a wide frequency range.
