Overview
The AD8539ARMZ-REEL is a dual-channel, low-power, precision auto-zero operational amplifier manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and features an extended industrial temperature range of -40°C to +125°C. The device utilizes an auto-zero architecture to achieve extremely low offset voltage (maximum 16 µV) and minimal input offset drift (0.03 µV/°C). Key electrical specifications include a gain bandwidth product of 430 kHz, a slew rate of 0.4 V/µs, and a maximum supply current of 210 µA per amplifier at 5.0 V. It is housed in an 8-lead MSOP package.
Feature Summary
- Auto-zero architecture ensures high precision with very low offset voltage and negligible drift over temperature variations.
- Low power consumption design suitable for battery-powered applications with supply currents under 215 µA per amplifier.
- Single-supply operation capability allows direct interfacing with low-voltage systems without requiring negative rails.
Applications
- Portable instrumentation
- Battery-powered devices
- Sensor interfaces
- Temperature measurement
Procurement Notes
Verify the specific ordering suffix REEL against the manufacturer's official documentation to confirm packaging type and quantity. Ensure the component matches the required automotive or commercial grade specifications if applicable. Cross-reference the datasheet revision B parameters with your design requirements before finalizing procurement decisions.
Selection Notes
Select this component when high DC accuracy is required in low-power environments. The dual-channel configuration reduces board space compared to single amplifiers. Consider the MSOP package dimensions for PCB layout constraints. Verify that the 430 kHz bandwidth meets the signal frequency requirements of the application.
Part Context
This part belongs to the AD8538/AD8539 family of low-power, precision auto-zero op amps. The AD8539 specifically denotes the dual-channel version, whereas the AD8538 is single-channel. Both share similar electrical characteristics but differ in channel count and pin configurations.
Replacement Considerations
Check for AD8539ARZ-REEL as a potential alternative in SOIC-8 packaging. Verify compatibility with AD8539ARMZ for tube-packaged variants. Ensure any substitute maintains the same auto-zero technology and low-offset specifications.
