ADA4077-4ARUZ-RL

Overview

The ADA4077-4ARUZ-RL is a quad precision operational amplifier from Analog Devices, housed in a 14-lead TSSOP package. It features a gain bandwidth product of 3.9 MHz and a slew rate of 1.2 V/µs. The device operates on dual supplies ranging from ±2.5 V to ±15 V with a typical supply current of 400 µA per amplifier. Key electrical characteristics include an input offset voltage of 50 µV maximum at 25°C, an input bias current of 1 nA maximum, and a common-mode rejection ratio exceeding 120 dB.

Feature Summary

• Extremely low offset voltage and drift for high accuracy signal processing
• Low input bias current and noise density suitable for sensitive applications
• Capacitive load stability exceeding 1000 pF without external compensation
• Immunity to output phase reversal even beyond the power supply rails

Applications

• Process control front-end amplifiers
• Optical network control circuits
• Precision sensors and controls
• Precision filters
• Sensor signal conditioning (thermocouples, RTDs, strain gages)

Procurement Notes

Verify the specific ordering suffix '-RL' corresponds to the required reel quantity of 2500 units as defined in the manufacturer's ordering guide. Confirm that the 'RU-14' package option matches the intended PCB footprint. Ensure compliance with MSL1 moisture sensitivity ratings for assembly processes.

Selection Notes

Select this component when multiple channels are required in a compact surface-mount form factor. It serves as a direct upgrade to previous OP07 family generations, offering significantly lower power consumption and higher bandwidth. Verify that the A-grade specifications meet the system's offset and drift requirements.

Part Context

This device belongs to the sixth generation of the industry-standard OP07 amplifier family. It replaces older precision amplifiers by providing superior performance in smaller packages. The quad configuration allows for cost-effective implementation of multi-channel instrumentation systems requiring high precision.
