ADA4077-4ARZ-RL

Overview

The ADA4077-4ARZ-RL is a quad precision operational amplifier from Analog Devices, housed in a 14-lead SOIC package. It features an offset voltage of 50 µV maximum and drift of 0.75 µV/°C. 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 parameters include a gain bandwidth product of 3.9 MHz, a slew rate of 1.2 V/µs, and a common-mode rejection ratio exceeding 120 dB.

Feature Summary

• Extremely low offset voltage and drift for high DC accuracy
• Low input bias current insensitive to temperature variations
• Stable operation with capacitive loads exceeding 1000 pF without external compensation
• Immunity to output phase reversal even beyond the power supply rails

Applications

• Process control front-end amplifiers
• Precision sensors and controls
• Optical network control circuits
• Instrumentation systems

Procurement Notes

Verify the specific ordering suffix '-RL' against the manufacturer's official documentation to confirm the reel quantity and packaging specifications. Ensure the component matches the required A grade performance levels for offset voltage and drift. Confirm that the 14-lead SOIC package dimensions align with the target PCB layout constraints.

Selection Notes

Select this component when multiple channels are required in a single package while maintaining high precision. The wide operating temperature range supports demanding environments. Consider the low power consumption relative to older generations if battery life or thermal management is critical. Verify that the 10 mA output drive capability meets the load requirements.

Part Context

This part belongs to the sixth generation of the industry-standard OP07 amplifier family. It replaces legacy devices by offering significantly improved bandwidth and lower power consumption within compact surface-mount packages. The series includes single, dual, and quad configurations to provide design flexibility across various application scales.
