AD8542ARMZ

Instrumentation, Op Amps, Buffer Amps Overview

The AD8542ARMZ is a dual-channel CMOS operational amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply voltage ranging from 2.7 V to 5.5 V with a typical supply current of 45 µA per amplifier. The device provides a gain bandwidth product of approximately 1 MHz and a slew rate of 0.92 V/µs at 5 V. Input bias current is typically 4 pA, ensuring high impedance performance. It is unity-gain stable and functions within an extended industrial temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the package marking code AVA corresponds to the 8-Lead MSOP configuration. Confirm RoHS compliance indicated by the Z suffix. Ensure the ordering quantity matches the standard tube packing for this specific part number variant.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when single-supply operation between 2.7 V and 5.5 V is required. It is appropriate for designs needing rail-to-rail signal swing and low power consumption. Consider the 8-lead MSOP package for space-constrained surface-mount layouts requiring extended temperature reliability.

Instrumentation, Op Amps, Buffer Amps Part Context

This dual-channel amplifier belongs to the AD854x family, which includes single (AD8541) and quad (AD8544) variants. All members share identical electrical characteristics but differ in channel count and package options. The AD8542 specifically integrates two independent amplifiers into one compact surface-mount footprint.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional substitutes include AD8542ARZ (SOIC package) and AD8542ARU (TSSOP package). These parts share identical pinouts and specifications; only the physical housing differs.
