In other words, the F / V conversion output is performed by retaining the Co terminal output with the hold
pulse. (Fig.3)
The Co output is transferred to CHf in the circuit and output through the buffer amp. The buffer amp output
(VOUT pin, pin (11)) changes to ±3VBE with 7VBE as the center, that is, within the range of 4VBE~10VBE,
according to the input frequency. Thus, the F / V conversion output is obtained by the output differential with
the potential of the Vref1 terminal (pin (12)), which has a reference voltage of 7VBE.
In addition, the conversion output can be amplified by the buffer amp using direct current. The gain in the Fig.2
example is a multiple of ((Ra + Rb) / Rb).
Although unlike Co, Ct, and Rt, the CHf value does not need to be precise, too large a value causes deterioration
in response characteristics.
Too small a value causes F / V conversion error due to leakage.
If the FG frequency is in the range of 500~1kHz, use the values indicated in the application circuits.
