    PRODUCT 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 500kHz and any FS input voltage up to ±30V. Linearity error is only 0.03% for a 250kHz FS, and operation is guaranteed over an 80dB dynamic range. The overall temperature coefficient (excluding the effects of external components) is typically ±50 ppm/. The AD654 operates from a single supply of 5V to 36V and consumes only 2.0mA quiescent current.

    The low drift (4μV/typ) input amplifier allows operation directly from small signals such as thermocouples or strain gauges while offering a high (250 MΩ) input resistance.Unlike most V/F converters, the AD654 provides a square-wave output, and can drive up to 12 TTL loads, optocouplers, long cables, or similar loads.

     

    PRODUCT HIGHLIGHTS

    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 frequency and a selectable pull-up resistor for the open-collector output stage.Any full scale input voltage range from 100mV to 10volts (or greater, depending on +Vs) can be accommodated 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.

    2. A minimum number of low cost external components are necessary.A single RC network is all that is required to setup any full scale frequency up to 500kHz and any full-scale input voltage up to +30V.

    3.Plastic packaging allows low cost implementation of the standard VFC applications: A/D conversion, isolated signal transmission, F/V conversion, phase-locked loops, and tuning switched-capacitor filters.

    4.Power supply requirements are minimal; only 2.0mA of quiescent current is drawn from the single positive supply from 4.5 volts to 36 volts. In this mode, positive inputs can vary from 0 volts (ground) to (+Vs-4) volts. Negative inputs can easily be connected for below ground operation.

    5.The versatile open-collector output stage can sink more than 10mA with a saturation voltage less than 0.4 volts.The Logic Common terminal can be connected to any level between ground (or -Vs) and 4 volts below +Vs.This allows easy direct interface to any logic family with either positive or negative logic levels.
