ADA4077-1ARZ-RL

Overview

The ADA4077-1ARZ-RL is a single-channel precision operational amplifier from Analog Devices, packaged in an 8-lead SOIC with reel packing. 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 a maximum input offset voltage of 50 µV (A grade) and a maximum drift of 0.55 µV/°C over the extended industrial temperature range of −40°C to +125°C.

Feature Summary

• Extremely low offset voltage and drift combined with low input bias current and noise for high DC accuracy
• Outputs remain stable with capacitive loads exceeding 1000 pF without requiring external compensation
• Immune to output phase reversal even when input voltages exceed the power supply rails
• MSL1 rated for compliance with stringent assembly processes and specified over an extended temperature range

Applications

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

Procurement Notes

Verify that the specific ordering suffix matches the required package type and tape-and-reel quantity. Confirm the A-grade offset specifications align with design requirements. Ensure the MSL1 rating meets the thermal profile constraints of the manufacturing process. Cross-reference the datasheet revision to validate all electrical parameters against the latest documentation.

Selection Notes

Select this component for applications demanding high precision and stability within a compact surface-mount footprint. The wide operating temperature range supports demanding environments. Consider the trade-off between the A-grade offset performance and the low power consumption relative to older generation amplifiers. Verify compatibility with the intended supply voltage range and load conditions.
