AD654 - Low Cost Monolithic Voltage-to-Frequency Converter
The AD654 is a monolithic V/F converter consisting of an input amplifier, a precision oscillator system, and a high current output stage.
A single RC network is all that is required to set up any full scale (FS) frequency up to 500 kHz and any FS input voltage up to ± 30 V.
Linearity error is only 0
