AD652KPZ

Overview

The AD652KPZ is a monolithic synchronous voltage-to-frequency converter manufactured by Analog Devices Inc. It operates within a supply voltage range of 12 V to 36 V, supporting both single and dual power configurations. The device features a full-scale frequency capability of 2 MHz and achieves an integral nonlinearity of ±0.02% FSR. Designed for surface-mount installation, it is housed in a 20-PLCC package with dimensions of 9x9 mm. The component functions reliably across an operating temperature range from 0°C to +70°C.

Feature Summary

• Monolithic synchronous architecture ensures high accuracy and stability during conversion processes.
• Integrated design eliminates the need for external timing components, simplifying circuit implementation.
• Supports bidirectional operation as both a voltage-to-frequency and frequency-to-voltage converter.

Applications

• Precision data acquisition systems requiring accurate analog signal digitization
• Industrial process control instrumentation
• Test and measurement equipment

Procurement Notes

Verify current availability status as the part may be discontinued or subject to limited supply constraints. Confirm RoHS compliance requirements against specific project standards, noting that some sources indicate non-compliance while others suggest adherence to ROHS3 specifications. Ensure the selected package variant matches the intended PCB layout and thermal management strategy for reliable long-term operation.

Selection Notes

Select this component when high linearity and wide dynamic range are critical for system performance. Consider the 20-PLCC package for surface-mount applications requiring robust mechanical stability. Evaluate the 12 V to 36 V supply requirement against available power rails. Verify that the 0°C to +70°C operating temperature range meets environmental conditions for the target deployment scenario.

Part Context

The AD652KPZ belongs to the AD652 series of voltage-to-frequency converters produced by Analog Devices. This family is known for its precision and reliability in industrial applications. The KPZ suffix denotes the specific package type and temperature rating, distinguishing it from other variants such as ceramic DIP or plastic DIP options within the same functional family.

Replacement Considerations

Check for direct pin-compatible substitutes within the AD652 series, such as the AD652AQ or AD652KJ, ensuring electrical parameters match. Verify package compatibility if transitioning between PLCC and DIP formats. Consult manufacturer documentation for any obsolescence notices or recommended alternative parts.
