PRODUCT DE SCRIPT ION
T he industry standard ADVFC32 is a low cost monolithic
voltage-to-frequency (V/F) converter or frequency-to-voltage
(F/V) converter with good linearity (0.01% max error at
10 kHz) and operating frequency up to 0.5 MHz. In the V/F
configuration, positive or negative input voltages or currents can
be converted to a proportional frequency using only a few exter-
nal components. For F/V conversion, the same components are
used with a simple biasing network to accommodate a wide
range of input logic levels.
T T L or CMOS compatibility is achieved in the V/F operating
mode using an open collector frequency output. T he pullup re-
sistor can be connected to voltages up to 30 volts, or to +15 V
or +5 V for conventional CMOS or T T L logic levels. T his resis-
tor should be chosen to limit current through the open collector
output to 8 mA. A larger resistance can be used if driving a high
impedance load.
Input offset drift is only 3ppm of full scale per
°
C, and full-
scale calibration drift is held to a maximum of 100 ppm/
°
C
(ADVFC32BH) due to a low T .C. Zener diode.
T he ADVFC32 is available in commercial, industrial, and ex-
tended temperature grades. T he commercial grade is packaged
in a 14-pin plastic DIP while the two wider temperature range
parts are packaged in hermetically sealed T O-100 cans.
PRODUCT HIGHLIGHT S
1. T he ADVFC32 uses a charge balancing circuit technique
(see Functional Block Diagram) which is well suited to high
accuracy voltage-to-frequency conversion. T he full-scale
operating frequency is determined by only one precision re-
sistor and capacitor. T he tolerance of other support compo-
nents (including the integration capacitor) is not critical.
Inexpensive
±
20% resistors and capacitors can be used with-
out affecting linearity or temperature drift.

2. T he ADVFC32 is easily configured to satisfy a wide range of
system requirements. Input voltage scaling is set by selecting
the input resistor which sets the input current to 0.25 mA at
the maximum input voltage.
3. T he 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 ADVFC32.
4. T he ADVFC32 is intended as a pin-for-pin replacement for
VFC32 devices from other manufacturers.
5. T he ADVFC32 is available in versions compliant with MIL-
ST D-883. Refer to the Analog Devices Military Products
Databook or current ADVFC32/883B data sheet for detailed
specifications.
