General Description

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 0.03% for a 250 kHz FS, and operation is guaranteed over an 80 dB dynamic range.
