OP2177ARZ-REEL7

Instrumentation, Op Amps, Buffer Amps Overview

The OP2177ARZ-REEL7 is a dual-channel precision operational amplifier from the Analog Devices OPx177 family, housed in an 8-lead SOIC package. It features a gain bandwidth product of 1.3 MHz and a slew rate of 0.7 V/µs. The device operates on dual supplies ranging from ±2.5 V to ±15 V with a supply current of 400 µA per amplifier. Key electrical characteristics include a maximum input offset voltage of 60 µV, a maximum input bias current of 2 nA, and a typical voltage noise density of 8 nV/√Hz at 1 kHz. It maintains stability with capacitive loads exceeding 1000 pF without external compensation.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific REEL7 suffix indicates tape and reel packaging when sourcing. Confirm the R suffix corresponds to the SOIC-8 package type required for your PCB layout. Ensure the operating environment falls within the specified -40°C to +125°C range to maintain guaranteed performance specifications. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring high DC precision combined with low noise and low input bias current. It serves as a direct replacement for previous generation high-voltage amplifiers where smaller surface-mount packaging is desired. Consider its internal input protection if the circuit may experience transient voltages exceeding supply rails. Evaluate the 1.3 MHz bandwidth against system speed requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

Instrumentation, Op Amps, Buffer Amps FAQ

Does the OP2177 exhibit phase reversal when input voltages exceed the supply rails?

No, the OP2177 is immune to output phase reversal even when input voltages exceed the positive or negative supply rails by up to 2.5 V.

What is the maximum capacitive load the OP2177 can drive without external compensation?

The outputs are stable with capacitive loads of over 1000 pF without the need for external compensation components.

How does the OP2177 handle input overvoltage conditions?

Internal 500 Ω series resistors protect the inputs, allowing signal levels several volts beyond either supply without harmful effects or phase reversal.
