PRODUCT DESCRIPTION

PRODUCT HIGHLIGHTS

The AD652 Synchronous Voltage-to-Frequency Converter

(SVFC) is a powerful building block for precision analog-to-

digital conversion, offering typical nonlinearity of 0.002%

(0.005% maximum) at a 100 kHz output frequency. The inher-

ent monotonicity of the transfer function and wide range of

clock frequencies allows the conversion time and resolution to

be optimized for specific applications.

1. The use of an external clock to set the full-scale frequency

allows the AD652 to achieve linearity and stability far supe-

rior to other monolithic VFCs. By using the same clock to

drive the AD652 and (through a suitable divider) also set the

counting period, conversion accuracy is maintained indepen-

dent of variations in clock frequency.

2. The AD652 Synchronous VFC requires only a single external

component (a noncritical integrator capacitor) for operation.

The AD652 uses a variation of the popular charge-balancing

technique to perform the conversion function. The AD652 uses

an external clock to define the full-scale output frequency,

rather than relying on the stability of an external capacitor. The

result is a more stable, more linear transfer function, with sig-

nificant application benefits in both single- and multichannel

systems.

3. The AD652 includes a buffered, accurate 5 V reference

which is available to the user.

4. The clock input of the AD652 is TTL and CMOS compat-

ible and can also be driven by sources referred to the negative

power supply. The flexible open-collector output stage pro-

vides sufficient current sinking capability for TTL and CMOS

logic, as well as for optical couplers and pulse transformers.

A capacitor-programmable one-shot is provided for selection

of optimum output pulse width for power reduction.

Gain drift is minimized using a precision low drift reference and

low TC on-chip thin-film scaling resistors. Furthermore, the ini-

tial gain error is reduced to less than 0.5% by the use of

laser-wafer-trimming.

5. The AD652 can also be configured for use as a synchronous

F/V converter for isolated analog signal transmission.

The analog and digital sections of the AD652 have been de-

signed to allow operation from a single-ended power source,

simplifying its use with isolated power supplies.

6. The AD652 is available in versions compliant with MIL-

STD-883. Refer to the Analog Devices Military Products

Databook or current AD652/883B data sheet for detailed

specifications.

The AD652 is available in five performance grades. The 20-lead

PLCC packaged JP and KP grades are specified for operation

over the 0°C to +70°C commercial temperature range. The

16-lead cerdip-packaged AQ and BQ grades are specified for

operation over the –40°C to +85°C industrial temperature

range, and the AD652SQ is available for operation over the full

–55°C to +125°C extended temperature range.
