AD825ARZ-REEL7

Instrumentation, Op Amps, Buffer Amps Overview

The AD825ARZ-REEL7 is a low-cost, general-purpose high-speed JFET input operational amplifier manufactured by Analog Devices Inc. It features a unity gain bandwidth of 26 MHz and a slew rate of 125 V/µs at ±15 V supplies. The device operates within a supply voltage range of ±5 V to ±15 V, drawing a quiescent current of 6.5 mA. Key electrical parameters include an input offset voltage of 1 mV, input bias current of 20 pA, and input voltage noise of 12 nV/√Hz. It provides a minimum output current of 50 mA and maintains stability when driving capacitive loads.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to the 7-inch tape and reel packaging option as defined in the manufacturer's ordering guide. Confirm RoHS compliance status indicated by the Z suffix. Ensure the component matches the 8-lead SOIC package dimensions and pinout configuration provided in the datasheet before integration into the design.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this amplifier for applications requiring high speed and low cost with stable AC performance over temperature. It is suitable for designs needing rail-to-rail input capability without phase reversal issues. Consider its 50 mA output drive for driving heavy resistive or capacitive loads directly. Evaluate the 26 MHz bandwidth against system frequency requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the AD825 series of high-speed JFET amplifiers. The series includes variants such as the standard tube-packaged AD825ARZ and the 16-lead wide SOIC versions like AD825ARZ-16. All variants share the same core operational characteristics but differ in physical package and shipping format.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes include other AD825 variants such as AD825ARZ (tube) or AD825ARZ-16 (16-lead package), provided the PCB footprint supports the change. Cross-family replacements require verification of pin compatibility and electrical parameter alignment.
