PRODUCT DESCRIPTION  
2. A minimum number of low cost external components are  
necessary. A single RC network is all that is required to set  
up any full scale frequency up to 500 kHz and any full-scale  
input voltage up to ±30 V.  
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. The  
overall temperature coefficient (excluding the effects of external  
components) is typically ±50 ppm/°C. The AD654 operates from  
a single supply of 5 V to 36 V and consumes only 2.0 mA quies-  
cent current.  
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 2.0 mA 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.  
The low drift (4 µV/°C typ) input amplifier allows operation  
directly from small signals such as thermocouples or strain gauges  
while offering a high (250 M) 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.  
5. The versatile open-collector output stage can sink more than  
10 mA 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.  
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 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 +VS) can be accommo-  
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.
