OP777ARMZ

Instrumentation, Op Amps, Buffer Amps Overview

The OP777ARMZ is a single-channel precision operational amplifier from Analog Devices, housed in an 8-lead MSOP package. It features a gain-bandwidth product of 0.7 MHz and a slew rate of 0.2 V/µs. The device operates on supply voltages ranging from 3 V to 30 V (single) or ±1.5 V to ±15 V (dual), with a maximum supply current of 350 µA. Key electrical specifications include a maximum input offset voltage of 200 µV, input bias current of 10 nA, common-mode rejection ratio of 110 dB, and power supply rejection ratio of 130 dB. It provides rail-to-rail output capability and maintains stability with capacitive loads exceeding 500 pF.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail output stage enables signal swing within 1 mV of both supply rails.
• Built-in 500 Ω internal series resistors protect inputs against overvoltage conditions without phase reversal.
• Micropower operation maintains low supply current consumption across the full operating temperature range.
• Unity-gain stable design ensures reliable performance in voltage follower configurations.

Instrumentation, Op Amps, Buffer Amps Applications

• Current sensing using shunt resistors
• Line-powered or battery-operated instrumentation
• Remote sensor signal conditioning
• Precision active filters

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix to confirm packaging format; the 'M' indicates MSOP package while 'Z' denotes RoHS compliance. Confirm availability status as distribution channels may list stock levels that vary. Ensure the component matches the required industrial temperature range of -40°C to +85°C for your application environment before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when single-supply operation down to 3 V is required alongside high precision. It serves as a direct upgrade to older bipolar amplifiers like the OP07, offering wider input/output voltage ranges. Consider the 8-lead MSOP package for space-constrained designs requiring surface-mount technology. Evaluate the trade-off between its 0.7 MHz bandwidth and low power consumption for your specific signal frequency requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

The OP777 is part of the OP777/OP727/OP747 family of precision micropower single-supply operational amplifiers. While the OP727 offers dual channels and the OP747 provides quad channels, the OP777 is configured as a single amplifier. All variants share identical electrical characteristics and pinout compatibility within their respective package types, allowing for scalable design architectures.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The OP777ARZ is a pin-compatible alternative available in an 8-lead SOIC package. Designers requiring tape and reel packaging should consider the OP777ARMZ-REEL variant. No other direct functional substitutes are explicitly documented in the provided datasheet.
