ADA4077-4ARZ-R7

Overview

The ADA4077-4ARZ-R7 is a quad precision operational amplifier from Analog Devices, housed in a 14-lead SOIC package. It features an A-grade offset voltage of 50 µV maximum at 25°C and a drift of 0.75 µV/°C across the -40°C to +125°C range. The device operates on dual supplies 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 input offset voltage and drift for high DC accuracy
• Low input bias current insensitive to temperature variations up to 125°C
• Capacitive load stability exceeding 1000 pF without external compensation
• Immunity to output phase reversal even beyond power supply settings

Applications

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

Procurement Notes

Verify the specific ordering suffix R7 corresponds to the reel packaging configuration required for your assembly line. Confirm that the A grade specifications align with your design's tolerance requirements for offset voltage and drift. Ensure the 14-lead SOIC footprint matches your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when multiple channels are needed in a compact surface-mount format. The wide operating temperature range supports demanding industrial environments. Consider the trade-off between the quad channel density and the thermal resistance characteristics inherent to the 14-lead SOIC package during system design.

Part Context

This part belongs to the sixth generation of the industry-standard OP07 amplifier family. It offers significant improvements over previous generations, including reduced power consumption and increased bandwidth. The device is designed to replace older precision amplifiers while providing superior performance in modern miniaturized electronic designs.

Replacement Considerations

Direct replacements within the same series include the ADA4077-4ARZ (tube packaging) or other variants like the ADA4077-4ARMZ if different package footprints are acceptable. Verify pin compatibility and electrical specifications match before substituting.
