A minimum number of low cost external components are The AD654 is a monolithic V/F converter consisting of an input necessary. A single RC network is all that is required to set amplifier, a precision oscillator system, and a high current output up any full scale frequency up to 500 kHz and any full-scale stage. A single RC network is all that is required to set up any input voltage up to 30 V. full scale (FS) frequency up to 500 kHz and any FS input voltage 3. Plastic packaging allows low cost implementation of the up to 30 V. Linearity error is only 0.03% for a 250 kHz FS, standard VFC applications: A/D conversion, isolated signal and operation is guaranteed over an 80 dB dynamic range. The transmission, F/V conversion, phase-locked loops, and tuning overall temperature coefficient (excluding the effects of external switched-capacitor filters. components) is typically 50 ppm/ C. The AD654 operates from 4. Power supply requirements are minimal only 2.0 mA of a single supply of 5 V to 36 V and consumes only 2.0 mA quies- quiescent current is drawn from the single positive supply cent current. from 4.5 volts to 36 volts. In this mode, positive inputs can The low drift (4 m V/ C typ) input amplifier allows operation vary from 0 volts (ground) to (+V 4) volts.

Unlike most 5. The versatile open-collector output stage can sink more than V/F converters, the AD654 provides a square-wave output, and 10 mA with a saturation voltage less than 0.4 volts.

This allows easy S S direct interface to any logic family with either positive or PRODUCT HIGHLIGHTS negative logic levels. 1. Packaged in both an 8-lead mini-DIP and an 8-lead SOIC package, the AD654 is a complete V/F converter requiring only an RC timing network to set the desired full-scale fre- quency and a selectable pull-up resistor for the open-collector output stage. Any full scale input voltage range from 100 mV to 10 volts (or greater, depending on +V ) can be accommo- S dated by proper selection of the timing resistor. The full- scale frequency is then set by the timing capacitor from the simple relationship, f = V/10 RC. REV. C Information furnished by Analog Devices is believed to be accurate and reliable.
