The ADVFC32 is a low-cost monolithic voltage-to-frequency (V/F) converter or frequency-to-voltage (F/V) converter with good linearity and high operating frequency.
The ADVFC32 from Analog Devices converts voltage to frequency (V/F) or frequency to voltage (F/V) with very high linearity (0.01 % max error at 10 kHz) and a full‑scale frequency range up to 0.5 MHz. It supports both TTL and CMOS logic levels, offers a 6‑decade dynamic range, and is available in commercial, industrial, and extended‑temperature grades.
The device is supplied in a 14‑lead plastic DIP (N‑14) and a hermetically sealed 10‑lead TO‑100 package. Detailed specifications include input voltage ranges, output logic levels, power‑supply requirements, temperature ranges, and ESD sensitivity. Application notes describe V/F and F/V configurations, bipolar operation, high‑noise‑immunity data links, and microprocessor‑driven A/D conversion.

The output can sink up to 8 mA.
The input offset drift is only 3 ppm per °C.
