Overview
The AD8542ARUZ-REEL is a dual-channel CMOS rail-to-rail general-purpose operational amplifier from Analog Devices. It operates on a single supply ranging from 2.7 V to 5.5 V with a low supply current of 45 µA per amplifier. The device features a gain-bandwidth product of 1 MHz, unity-gain stability, and no phase reversal. Input bias current is typically 4 pA, supporting high source impedance applications. It is specified over an extended industrial temperature range of -40°C to +125°C and comes in an 8-lead TSSOP package.
Feature Summary
- Rail-to-rail input and output voltage swing capability
- Low power consumption with 45 µA supply current per amplifier
- High input impedance with very low input bias currents
- Unity-gain stable with no phase reversal
Applications
- ASIC input or output amplifiers
- Sensor interfaces
- Piezoelectric transducer amplifiers
- Medical instrumentation
- Portable systems
Procurement Notes
Verify the specific ordering suffix RUZ against official documentation to confirm the 8-lead TSSOP package and reel packing quantity. Ensure the component meets RoHS compliance standards as indicated by the Z suffix. Confirm that the automotive qualification status matches project requirements, noting that only W-qualified models are designated for automotive use.
Selection Notes
Select this component for designs requiring low power operation with rail-to-rail signal handling. It is suitable for battery-powered portable systems where minimizing current drain is critical. The wide input common-mode range and high input impedance make it appropriate for interfacing with high-impedance sensors and piezoelectric elements without significant signal loss.
Part Context
This part belongs to the AD854x family of CMOS rail-to-rail amplifiers, which includes single (AD8541), dual (AD8542), and quad (AD8544) channel variants. The family is designed to provide improved performance at lower supply voltages compared to previous generations while maintaining a 1 MHz bandwidth. The AD8542 specifically offers two independent amplifiers in a compact surface-mount package.
Replacement Considerations
Check the Ordering Guide for other packaging options like AD8542ARMZ or AD8542ARZ if different footprints are required. Automotive-grade equivalents are available as AD854xW models, but specifications may differ from commercial versions.
