PRODUCT DESCRIPTION  
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  
voltage 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.  
The AD650JN and AD650KN are offered in plastic 14-lead DIP  
packages. 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 temperature range  
(0°C to 70°C). For industrial temperature range (−25°C to  
+85°C) applications, the AD650AD and AD650BD are offered  
in ceramic packages. The AD650SD is specified for the full  
−55°C to +125°C extended temperature range.  
PRODUCT HIGHLIGHTS  
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  
conversions. 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.  
1. Can operate at full-scale output frequencies up to 1 MHz  
(in addition to having very high linearity).  
2. Can be configured to accommodate bipolar, unipolar, or  
differential input voltages, or unipolar input currents.  
3. TTL or CMOS compatibility is achieved by using an open  
collector frequency output. The pull-up resistor can be  
connected to voltages up to 30 V.  
4. The same components used for V/F conversion can also be  
used for F/V conversion by adding a simple logic biasing  
network and reconfiguring the AD650.  
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.  
5. Separate analog and digital grounds prevent ground loops  
in real-world applications.  
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.  
6. Available in versions compliant with MIL-STD-883.
