INA333SHKJ

Overview

The INA333SHKJ is a micro-power, zero-drift instrumentation amplifier from Texas Instruments. It features rail-to-rail output and operates on supply voltages ranging from 1.8 V to 5.5 V. Key electrical parameters include a gain bandwidth product of 350 kHz, a slew rate of 160 mV/us, and an input offset voltage of 25 uV. The device draws 198 uA of operating current and offers a common-mode rejection ratio of 100 dB. It is housed in an 8-pin CFP package and supports operation temperatures from -55°C to +210°C.

Feature Summary

• Zero-drift architecture ensures high precision with minimal offset voltage drift over temperature.
• Rail-to-rail output capability allows for maximum dynamic range in low-voltage single-supply applications.
• Micro-power consumption design enables efficient operation in battery-powered systems.

Applications

• Precision sensor signal conditioning
• Medical instrumentation
• Industrial process control

Procurement Notes

Verify the specific suffix HKJ to confirm the CFP-8 package and extended temperature range. Confirm availability status as some sources indicate scheduled obsolescence. Ensure compatibility with your PCB footprint for the ceramic flat pack configuration. Check for any recent production change notices regarding reliability data or material composition updates before finalizing procurement plans.

Selection Notes

Select this component when zero-drift performance is critical alongside low power consumption. The rail-to-rail output distinguishes it from standard instrumentation amplifiers that may not utilize the full supply range. Consider the CFP package constraints for thermal management and board space. Compare against the INA333SHKQ if a different package type is required for assembly processes.

Part Context

This part belongs to the INA333 family of precision instrumentation amplifiers. It shares core specifications with variants like the INA333SHKQ but differs in packaging. The SHKJ designation specifically denotes the ceramic flat pack (CFP) housing suitable for high-reliability environments. It complements other TI op-amps like the OPA2333 series in mixed-signal designs.

Replacement Considerations

The INA333SHKQ is a direct functional substitute within the same family, offering identical electrical characteristics but in a different package configuration. Verify pinout compatibility and mechanical fit before substitution. No other cross-family replacements are confirmed in public documentation.
