5962-8777101M3A

Overview

The Analog Devices 5962-8777101M3A is a military-grade quad operational amplifier, equivalent to the OP400ATCMDA. It features four precision amplifiers with low input offset voltage (max 150 μV) and low drift (max 1.2 μV/°C). The device operates within a temperature range of -55°C to +125°C. Key electrical characteristics include a maximum supply current of 725 μA per amplifier, a gain bandwidth product of 500 kHz, and an input bias current of max 3 nA. It provides high open-loop gain (min 5000 V/mV) and stable operation with capacitive loads up to 10 nF.

Feature Summary

• Monolithic quad architecture delivering precision performance comparable to single-channel devices while saving space.
• Extremely low input offset voltage and drift guaranteed over the full military temperature range.
• Low power consumption with total current draw less than that of a single standard op amp.
• Inherent stability at all gains with capability to drive large capacitive loads without oscillation.

Applications

• Dual low power instrumentation amplifiers
• Bipolar current transmitters
• Differential output instrumentation amplifiers
• Multiple output tracking voltage references

Procurement Notes

Verify the specific grade suffix against the ordering guide to confirm temperature range and package type. Ensure compatibility with MIL-PRF-38535 requirements if applicable. Confirm RoHS status as military parts may differ from commercial equivalents. Check for availability of the specific die or packaged form factor required for the design.

Selection Notes

Select this component when multiple precision channels are needed in a compact form factor. It is suitable for applications requiring low noise and high common-mode rejection. Consider the 14-lead ceramic dual in-line package for rugged environments. Evaluate the trade-off between the low quiescent current and the required slew rate for dynamic signals.

Part Context

This part belongs to the OP400 family, which was designed as the first monolithic quad op amp with OP77-type performance. It eliminates the need for offset nulling through on-chip Zener zap trimming. The device offers significant improvements over industry-standard single op amps like the OP07 in terms of channel density and power efficiency.

Replacement Considerations

The datasheet lists SMD Part Number 5962-8777101MCA as an equivalent military processed device. Verify pinout compatibility and thermal resistance specifications before substitution. Ensure the replacement meets the same environmental qualification standards.
