PRODUCT DESCRIPTION  
The AD650JN and AD650KN are offered in a plastic 14-lead  
DIP package. The AD650JP is available in a 20-lead plastic  
leaded chip carrier (PLCC). Both plastic packaged versions of the  
AD650 are specified for the commercial (0°C to +70°C) tempera-  
ture range. For industrial temperature range (–25°C to +85°C)  
applications, the AD650AD and AD650BD are offered in a  
ceramic package. The AD650SD is specified for the full –55°C  
to +125°C extended temperature range.  
The AD650 V/F/V (voltage-to-frequency or frequency-to-voltage  
converter) provides a combination of high frequency operation  
and low nonlinearity previously unavailable in monolithic form.  
The inherent monotonicity of the V/F transfer function makes  
the AD650 useful as a high-resolution analog-to-digital converter.  
A flexible input configuration allows a wide variety of input volt-  
age and current formats to be used, and an open-collector output  
with separate digital ground allows simple interfacing to either  
standard logic families or opto-couplers.  
PRODUCT HIGHLIGHTS  
1. In addition to very high linearity, the AD650 can operate at  
full-scale output frequency up to 1 MHz. The combination of  
these two features makes the AD650 an inexpensive solution  
for applications requiring high resolution monotonic A/D  
conversion.  
The linearity error of the AD650 is typically 20 ppm (0.002%  
of full scale) and 50 ppm (0.005%) maximum at 10 kHz full  
scale. This corresponds to approximately 14-bit linearity in an  
analog-to-digital converter circuit. Higher full-scale frequencies  
or longer count intervals can be used for higher resolution con-  
versions. The AD650 has a useful dynamic range of six decades  
allowing extremely high resolution measurements. Even at 1 MHz  
full scale, linearity is guaranteed less than 1000 ppm (0.1%) on  
the AD650KN, BD, and SD grades.  
2. The AD650 has a very versatile architecture that can be con-  
figured to accommodate bipolar, unipolar, or differential  
input voltages, or unipolar input currents.  
3. TTL or CMOS compatibility is achieved using an open  
collector frequency output. The pull-up resistor can be  
connected to voltages up to +30 V, or +15 V or +5 V for  
conventional CMOS or TTL logic levels.  
In addition to analog-to-digital conversion, the AD650 can be used  
in isolated analog signal transmission applications, phased locked-  
loop circuits, and precision stepper motor speed controllers. In  
the F/V mode, the AD650 can be used in precision tachometer  
and FM demodulator circuits.  
4. The same components used for V/F conversion can also be  
used for F/V conversion by adding a simple logic biasing net-  
work and reconfiguring the AD650.  
The input signal range and full-scale output frequency are user-  
programmable with two external capacitors and one resistor.  
Input offset voltage can be trimmed to zero with an external  
potentiometer.  
5. The AD650 provides separate analog and digital grounds.  
This feature allows prevention of ground loops in real-world  
applications.  
6. The AD650 is available in versions compliant with MIL-  
STD-883. Refer to the Analog Devices Military Products  
Databook or current AD650/883B data sheet for detailed  
specifications.
