AD654JNZ/+

Overview

The AD654JNZ is a monolithic 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 supplies. The device supports a full-scale frequency of 500 kHz with an integral nonlinearity of ±0.4% FSR. It functions reliably across an operating temperature range from -40°C to +85°C. The component is housed in an 8-pin PDIP package designed for through-hole mounting.

Feature Summary

• Performs bidirectional conversion between analog voltage inputs and digital frequency outputs.

Applications

• Data acquisition systems requiring analog-to-digital interface

Procurement Notes

Verify the exact suffix designation on official documentation, as standard listings typically reference AD654JNZ. Confirm current availability status directly with authorized distributors or the manufacturer, as supply constraints may apply. Ensure the selected variant matches the required packaging and temperature specifications for the intended design environment.

Selection Notes

Select this component when a single-chip solution for both voltage-to-frequency and frequency-to-voltage conversion is required. Verify that the input signal range aligns with the specified full-scale parameters. Consider the PDIP-8 package constraints for PCB layout and thermal management during the design phase.

Part Context

This part belongs to the AD654 series of precision converters. It serves as a specialized integrated circuit for signal conditioning tasks where high linearity and wide dynamic range are necessary.
