OP27AZ overview

OP27AZ is a component documented by Analog Devices. The PDF description identifies it as "Low-Noise, Precision Operational Amplifier 9/01-Data Sheet changed from REV. 0 to REV. A." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.

Specifications and operating details

The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.

  • Exceptionally low noise, e n = 3.5 nV/√Hz, at 10 Hz, a low 1/f noise corner frequency of 2.7 Hz, and high gain (1.8 million), allow accurate high-gain amplification of low-level signals.
  • A gain-bandwidth product of 8 MHz and a 2.8 V/ µsec slew rate provides excellent dynamic accuracy in high-speed, data- acquisition systems.
  • A guaranteed swing of ± 10 V into 600 Ω and low output distortion make the OP27 an excellent choice for professional audio applications. (Continued on page 7) Q2B R2* Q2AQ1A Q1B R1* R3 18 VOS ADJ.

Engineering review checklist

  • Verify supply range, input common-mode range and output swing at the required load.
  • Check offset, bias current, noise, bandwidth, slew rate and stability for the intended feedback network.
  • Review supply decoupling, source impedance, capacitive-load behavior and thermal limits in the final layout.

Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
