AD598JRZ

Overview

The AD598JRZ is a dedicated LVDT signal conditioner integrated circuit manufactured by Analog Devices Inc. It operates on a single 13 V supply with a typical current consumption of 15 mA. The device accepts an input voltage range from 100 mV to 3.5 V and provides a corresponding output voltage between 2.1 V and 24 V. It features an internal oscillator and voltage reference, housed in a 20-SOIC surface-mount package. The component supports a maximum output current of 30 mA and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Integrates internal oscillator and precision voltage reference for simplified circuit design
• Provides direct interface capability for Linear Variable Differential Transformers (LVDT)
• Delivers linear voltage output proportional to core displacement position

Applications

• Industrial position sensing systems
• Automotive suspension and steering angle measurement
• Robotics joint position feedback

Procurement Notes

Verify the specific suffix JRZ corresponds to the SOIC-20 package and commercial temperature grade when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations prior to integration into final assemblies.

Selection Notes

Select this component for applications requiring precise LVDT signal conditioning without external excitation sources. Ensure the required output voltage swing aligns with the 2.1 V to 24 V specification. Verify that the operating environment remains within the 0°C to +70°C range for optimal performance.
