AD654JNZ

Overview

The AD654JNZ is a voltage-to-frequency and frequency-to-voltage converter manufactured by Analog Devices Inc. It operates within a supply voltage range of 4.5 V to 36 V using dual power sources. The device supports a full-scale frequency of 500 kHz with an integral nonlinearity of +/- 0.4% FSR. It functions in temperatures from -40°C to +85°C and is housed in an 8-PDIP through-hole package.

Feature Summary

• Performs bidirectional conversion between analog voltage signals and digital frequency outputs
• Provides high linearity performance for precision signal processing applications

Applications

• Industrial process control systems requiring precise signal digitization
• Data acquisition modules converting sensor voltage outputs to frequency domains
• Frequency modulation circuits in communication equipment

Procurement Notes

Verify current availability status as the component may be subject to limited supply or discontinuation. Confirm RoHS compliance and specific manufacturing site details via official datasheets before integration. Check for product change notifications regarding fabrication updates.

Selection Notes

Select this component when dual-supply operation is feasible and through-hole mounting is required. Ensure input voltage ranges align with the specified 4.5 V to 36 V limits. Consider thermal management requirements for the industrial temperature range during system design.

Part Context

This part belongs to the AD654 series of converters, designed for cost-effective V/F and F/V conversion tasks. It serves as a bridge between analog sensing elements and digital processing units, offering a robust solution for environments where direct ADC interfaces are unsuitable due to noise or distance constraints.

Replacement Considerations

Check for AD654 variants with different suffixes indicating package or temperature changes. Verify pin compatibility if substituting with other V/F converters from the same manufacturer family.
