HPA00141AIDBVRG4

Overview

The HPA00141AIDBVRG4 is a single-channel operational amplifier from the Texas Instruments zero-drift series. It operates on a single 1.8-V supply and features microPower CMOS architecture. The device utilizes auto-zero technology to achieve high precision with low offset voltage and drift. It is housed in an SOT-23-5 package, designed for surface-mount installation. This component provides rail-to-rail input and output capabilities, ensuring optimal signal swing within the supply range.

Feature Summary

• Zero-drift architecture utilizing auto-zero techniques for enhanced DC accuracy
• MicroPower CMOS design optimized for low current consumption
• Single 1.8-V supply operation capability
• Rail-to-rail input and output performance

Applications

• Battery-powered portable instrumentation
• Precision sensor signal conditioning
• Medical devices requiring low offset stability
• Industrial control systems with limited power budgets

Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance and RoHS standards during procurement. Confirm the SOT-23-5 package availability matches your PCB footprint requirements. Ensure the operating temperature range aligns with your system's environmental conditions. Cross-reference the manufacturer datasheet for handling and storage precautions related to moisture sensitivity levels.

Selection Notes

Select this component when ultra-low offset voltage and drift are critical alongside minimal power usage. It serves as a suitable replacement for standard op-amps where temperature stability impacts accuracy. Consider the rail-to-rail I/O feature if maximizing dynamic range on a low voltage supply is necessary. Evaluate the microPower characteristics against total system energy constraints before finalizing the design.

Part Context

This part belongs to the HPA00141 family of zero-drift amplifiers. It shares architectural similarities with the OPA333 series but may offer distinct performance trade-offs specific to the HPA designation. The device represents Texas Instruments' approach to combining high precision with low power consumption in a compact surface-mount package.

Replacement Considerations

The OPA333AIDBVR is a documented alternative within the same zero-drift family. Verify pin compatibility and electrical parameter overlaps before substitution. Check for any differences in supply voltage ranges or package marking between the HPA and OPA series variants.
