AD8509ARU-REEL

Overview

The AD8509ARU-REEL is a quad precision CMOS operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail input and output capabilities, supporting single supply voltages from 2.7 V to 5.5 V or dual supplies of ±1.35 V to ±2.75 V. Key electrical parameters include a gain-bandwidth product of 4 MHz, a slew rate of 2.5 V/µs, and an input offset voltage of 2 mV maximum. The device operates with a quiescent current of 600 µA per channel and maintains operation across an extended temperature range of -40°C to +125°C. Packaged in a TSSOP-14 surface-mount format, it offers high common-mode rejection and low noise characteristics suitable for precision applications.

Feature Summary

• Quad configuration providing four independent precision amplifiers in a single package
• Rail-to-rail input and output functionality maximizing dynamic signal swing
• CMOS technology ensuring low power consumption and high input impedance
• Extended industrial temperature rating for reliable performance in harsh environments

Applications

• Battery-powered sensor signal conditioning circuits
• Precision data acquisition systems requiring low power
• Active filtering applications in portable instrumentation
• Medical equipment requiring high accuracy and low noise

Procurement Notes

Verify the specific suffix 'REEL' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the supplier provides valid traceability records for quality assurance purposes. Cross-reference the full part number against the latest datasheet revision to confirm pinout and electrical specifications match design requirements.

Selection Notes

Select this component when a quad amplifier topology is required alongside strict power budget constraints. The rail-to-rail I/O capability makes it suitable for low-voltage single-supply designs where signal swing maximization is critical. Consider the 4 MHz bandwidth and 2.5 V/µs slew rate for moderate-speed signal processing tasks. Evaluate thermal management needs given the TSSOP-14 package size and operating temperature range.

Part Context

This component belongs to the AD8509 series of precision operational amplifiers designed for general-purpose analog signal processing. It serves as a multi-channel solution within Analog Devices' portfolio of low-power CMOS amplifiers. The quad architecture allows designers to consolidate multiple functional blocks into a compact footprint, reducing board space compared to using individual single-channel devices.
