AD8512TRZ-EP-R7

Overview

The AD8512TRZ-EP-R7 is a dual-precision JFET operational amplifier from Analog Devices, designed for high-performance applications. It features low offset voltage (1.0 mV max at ±15 V), low input bias current (25 pA typical), and low noise (8.0 nV/√Hz). The device operates on dual supplies ranging from ±5 V to ±15 V and supports a military temperature range of −55°C to +125°C. Key dynamic specifications include an 8 MHz gain bandwidth product, a 20 V/µs slew rate, and fast settling time of 500 ns to 0.1%. It is housed in an 8-lead narrow SOIC package.

Feature Summary

• Enhanced Product qualification supporting defense and aerospace applications under AQEC standards
• Military temperature operation spanning from −55°C to +125°C
• Controlled manufacturing baseline with single assembly and fabrication sites
• No phase reversal when input voltages exceed the maximum common-mode voltage range

Applications

• Instrumentation
• Multipole filters
• Precision current measurement
• Photodiode amplifiers
• Military communication
• Avionics

Procurement Notes

Verify that the specific ordering suffix matches the required reel configuration. Confirm the Enhanced Product status aligns with project requirements for controlled manufacturing baselines. Ensure compatibility with the specified military temperature range and package dimensions during integration.

Selection Notes

Select this component for circuits requiring high impedance sensor amplification and precise current measurements using shunts. Its combination of dc precision, low noise, and fast settling time ensures superior accuracy in flight instruments and aviation equipment. Consider its stability with substantial capacitive loads for high-performance filter designs.

Part Context

This part belongs to the AD8512-EP family of precision, very low noise, low input bias current, wide bandwidth JFET operational amplifiers. It is distinguished by its Enhanced Product designation, which provides additional reliability data and manufacturing controls suitable for demanding environments compared to standard commercial variants.

Replacement Considerations

Standard AD8512 variants lack the Enhanced Product manufacturing controls and specific qualification data required for defense and aerospace applications. Verify if the non-EP version meets the necessary environmental and reliability standards for the intended use case.
