OP1177ARMZ-R7

Instrumentation, Op Amps, Buffer Amps Overview

The OP1177ARMZ-R7 is a single-channel precision operational amplifier from the Analog Devices OPx177 family, housed in an 8-lead MSOP 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 input 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 either supply without phase reversal.
• Outputs remain stable with capacitive loads exceeding 1000 pF without requiring external compensation.
• Low input bias current ensures performance remains relatively insensitive to ambient temperature variations up to 125°C.

Instrumentation, Op Amps, Buffer Amps Applications

• Wireless base station control circuits
• Optical network control circuits
• Precision filters
• Thermocouple and RTD sensor signal conditioning

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the RM suffix indicates tape and reel packaging only. Confirm the specific ordering code matches the required channel count and package type. Check for RoHS compliance status as indicated in official documentation before finalizing procurement specifications.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high DC accuracy and low noise are critical. The wide operating temperature range supports demanding environments. Ensure the application does not require internal switching capabilities, as this is a linear amplifier designed for signal processing rather than power management.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPx177 series, which includes single (OP1177), dual (OP2177), and quad (OP4177) variants. The family represents a fourth-generation evolution of the industry-standard OP07 amplifier, offering improved bandwidth and lower power consumption while maintaining high precision in surface-mount packages.
