AD625SD

Instrumentation, Op Amps, Buffer Amps Overview

The AD625SD is a precision instrumentation amplifier in a 16-lead ceramic DIP package, rated for an extended temperature range of –55°C to +125°C. It features user-programmable gains from 1 to 10,000 using three external resistors. Key electrical specifications include a maximum gain error of 0.035%, a gain temperature coefficient of 5 ppm/°C, and a low input offset voltage of 50 µV. The device offers a 25 MHz gain-bandwidth product, 4 nV/√Hz voltage noise at 1 kHz, and a slew rate of 5 V/µs.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Supports software programmable gain amplifier configurations with 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
• Utilizes proprietary design to achieve low input voltage noise

Instrumentation, Op Amps, Buffer Amps Applications

• Circuits requiring nonstandard gains not easily achievable with standard devices
• Low cost, precision software programmable gain amplifier designs
• High precision industrial applications requiring extended temperature stability

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix SD indicates the 16-lead Ceramic DIP package and the S grade for the –55°C to +125°C operating range. Confirm that the ordering part number matches the required military or standard drawing specifications if applicable. Ensure the source documentation explicitly supports the package type and temperature rating before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the AD625SD when extended temperature operation is required alongside high precision. The S grade ensures performance within specified limits across the full –55°C to +125°C range. Consider the external resistor tolerance as it primarily determines overall gain accuracy and temperature coefficient. Evaluate the need for independent offset nulling capabilities for the specific application requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

The AD625 series includes multiple grades (A, B, C, J, K, S) and packages (Ceramic DIP, Plastic DIP, LCC). The AD625SD specifically denotes the S grade variant housed in a 16-lead Ceramic DIP package. This variant is distinct from commercial grades like the AD625JN which operate over a narrower temperature range.
