AD654 - Low Cost Monolithic Voltage-to-Frequency Converter

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.

Key Features

  • Low Cost Single or Dual Supply, 5 V to 36 V, ؎5 V to ؎18 V Full-Scale Frequency Up to 500 kHz Minimum Number of External Components Needed Versatile Input Amplifier Positive or Negative Voltage Modes Negative Current Mode High Input Impedance, Low Drift Low Power: 2.0 mA Quiescent Current Low Offset: 1 mV Low Cost Monolithic Voltage-to-Frequency Converter AD654.
