• Provides very low input bias current suitable for high impedance sources
• Supports common-mode voltage including the positive power supply rail

Applications

• Driving analog-to-digital converter inputs
• Buffering digital-to-analog converter outputs
• High-side signal conditioning
• Instrumentation-quality photodiode amplification

Procurement Notes

Verify that the specific ordering suffix matches the required reel quantity configuration. Confirm the package type corresponds to the 5-Lead TSOT variant. Ensure the RoHS compliant designation aligns with project environmental requirements. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity before procurement.

Selection Notes

Select this component when a single-channel JFET input amplifier is required for precision applications. It is appropriate for designs needing unity gain stability and wide bandwidth. Consider its low power consumption and ability to drive capacitive loads directly. Evaluate thermal resistance characteristics if operating near maximum temperature limits.

Part Context

This device belongs to the ADA4000 series of low-cost precision amplifiers. The series includes dual and quad channel variants offering similar electrical characteristics in different package configurations. The AUJZ suffix specifically denotes the 5-Lead TSOT package option, providing a compact footprint for space-constrained PCB layouts compared to standard SOIC packages.

FAQ

Does the ADA4000-1 experience output phase reversal?

Yes, phase reversal can occur if the input voltage exceeds the maximum common-mode voltage. This behavior is temporary and resolves once the common-mode voltage returns to the valid range.

What is the maximum capacitive load the device can drive?

The device is stable and capable of driving up to 1000 pF of capacitive loads without oscillations in unity gain configurations.
