5962-87719012A

Overview

The AD625 is a precision programmable gain instrumentation amplifier manufactured by Analog Devices Inc. The 5962-87719012A variant operates within an extended temperature range of -55°C to +125°C and utilizes a 20-terminal Leadless Chip Carrier package. It supports user-programmed gains from 1 to 10,000 via three external resistors. Key electrical specifications include a maximum gain error of 0.02%, a gain temperature coefficient of 5 ppm/°C, and a low input offset voltage of 25 µV. The device features a 25 MHz gain bandwidth product, 4 nV/√Hz input voltage noise at 1 kHz, and a 5 V/µs slew rate.

Feature Summary

• Supports software programmable gain amplifier configurations using CMOS multiplexers without switch ON resistance affecting accuracy
• Provides independent input and output offset nulling terminals for high precision applications
• Maintains common-mode rejection independent of feedback resistor matching
• Offers proprietary design achieving low input voltage noise of 4 n/√Hz at 1 kHz

Applications

• Circuits requiring nonstandard gains not easily achievable with standard devices
• Low cost, precision software programmable gain amplifiers
• High precision data acquisition systems
• Industrial sensor signal conditioning

Procurement Notes

Verify the specific military drawing availability and ensure the 20-terminal LCC package matches the target footprint. Confirm that the extended temperature grade meets the operational requirements. Check for RoHS compliance status as manufacturing processes may vary. Validate pinout compatibility during integration to avoid circuit errors.

Selection Notes

Select this component when fixed or programmable gains up to 10,000 are required with minimal external component count. Consider the 20-terminal LCC package for space-constrained designs. Evaluate the need for independent offset nulling if high precision is critical across varying temperatures. Ensure external resistor selection aligns with desired gain accuracy and temperature stability.

Part Context

This part belongs to the AD625 family of precision instrumentation amplifiers designed for versatile gain control. It serves as a robust solution for applications demanding high CMRR and low drift. The military-grade variant ensures reliability in harsh environments. It complements other Analog Devices signal chain components for complete system integration.

Replacement Considerations

Direct substitutes include other AD625 variants such as the AD625SE/883B for similar military specifications. Verify package dimensions and pinout compatibility before substitution. Ensure thermal performance meets the application's extended temperature requirements.
