OP1177AR-REEL

Instrumentation, Op Amps, Buffer Amps Overview

The OP1177AR-REEL is a single-channel precision operational amplifier from Analog Devices, housed in an 8-lead SOIC package. It features a maximum offset voltage of 60 μV and a drift of 0.7 μV/°C. 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 parameters include a gain bandwidth product of 1.3 MHz, a slew rate of 0.7 V/μs, and a typical voltage noise density of 8 nV/√Hz at 1 kHz.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Internal input protection allows signal levels several volts beyond the supply rails without causing phase reversal.
• Outputs remain stable when driving capacitive loads exceeding 1000 pF without requiring external compensation components.
• Low input bias current ensures minimal error contribution even when used with high source resistance values.

Instrumentation, Op Amps, Buffer Amps Applications

• Wireless base station control circuits
• Optical network control circuits
• Precision filters
• Strain bridges

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the ordering suffix matches the required tape and reel packaging format for automated assembly. Confirm the specific temperature range specifications align with the intended operating environment. Ensure the component meets all relevant RoHS compliance standards before final integration into the design.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring high DC accuracy combined with low power consumption. The wide operating temperature range supports demanding environments where system temperatures may rise significantly. Consider the internal overvoltage protection if the application involves potential signal excursions beyond the supply rails.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPx177 family, which includes dual (OP2177) and quad (OP4177) variants. The family represents a fourth-generation evolution of industry-standard amplifiers, offering improved performance metrics compared to predecessors like the OP07 and OP177 while maintaining compatibility with surface-mount packaging constraints.
