ADA4077-2BRZ-RL

Overview

The ADA4077-2BRZ-RL is a dual high precision operational amplifier from Analog Devices, packaged in an 8-lead SOIC. It features a gain bandwidth product of 3.9 MHz at ±5 V 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. It offers low input bias current (maximum 1 nA) and low voltage noise density (6.9 nV/√Hz). The B grade variant specifies a maximum offset voltage of 25 µV and drift of 0.25 µV/°C.

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 power supply settings

Applications

• Sensor signal conditioning such as thermocouples, RTDs, and strain gauges
• Process control front-end amplifiers
• Precision filters and instrumentation circuits
• Optical and wireless transmission systems requiring precision diode power measurement

Procurement Notes

Verify the specific ordering suffix to confirm the reel quantity and package type. Confirm that the component grade matches the required offset voltage specifications for your design. Ensure compatibility with standard surface mount assembly processes given the MSL1 rating. Cross-reference the datasheet revision to validate electrical characteristics against your system requirements.

Selection Notes

Select this component when designing circuits requiring high precision with minimal power consumption. The dual configuration is suitable for applications needing two independent channels in a compact footprint. Consider the extended industrial temperature range for demanding environments. Evaluate the low noise characteristics for sensitive analog signal paths where signal integrity is critical.

Part Context

This part belongs to the sixth generation of the industry-standard OP07 amplifier family. It succeeds previous generations like the OP177 by offering significantly improved bandwidth and lower power dissipation. The device maintains the legacy of high precision while integrating modern performance metrics into a small surface-mount package.

Replacement Considerations

Direct functional replacements within the same series include the ADA4077-2ARZ-RL for A grade specifications or the ADA4077-2ARMZ-RL for MSOP packaging.
