Frequently Asked Questions
What is the input voltage noise of the OPA827AID?
The OPA827AID features an ultra-low input voltage noise density of 4 nV/√Hz, making it one of the quietest JFET-input op-amps available. This low noise characteristic is critical for high-resolution data acquisition, precision instrumentation, and sensitive sensor front-end designs.
What are the typical applications for the OPA827AID?
The OPA827AID is ideal for precision instrumentation amplifiers, medical diagnostic equipment, photodiode transimpedance amplifiers, active filters, and data acquisition systems. Its JFET input with 10 pA max bias current suits high-impedance sources, and the 114 dB typical CMRR ensures excellent rejection of common-mode interference in industrial and laboratory environments.
What package options are available for the OPA827AID and what is the typical price?
The OPA827AID is available in the SOIC-8 (Small Outline Package) through-hole-compatible surface mount package, suitable for standard PCB assembly processes. It is priced from approximately $6.93 per unit and is available worldwide with global shipping. It is RoHS compliant and Pb-free, with Texas Instruments projecting a 15-year product lifecycle.
How does the OPA827AID compare to alternative JFET op-amps like OPA827AIDR?
The OPA827AID (tube packaging) and OPA827AIDR (tape-and-reel packaging) are identical in electrical specifications, both offering 4 nV/√Hz noise, 104 dB min CMRR, and 10 pA max bias current at 25°C. The choice depends on assembly volume: the AIDR variant suits high-volume automated SMT production, while the AID suits prototyping and lower-volume builds.
