Frequently Asked Questions
What are the key electrical specifications of the OPA4227UA?
The OPA4227UA features an input offset voltage of 25 µV max, voltage noise of 8 nV/√Hz, gain-bandwidth product of 8 MHz, slew rate of 2.3 V/µs, and operates from ±2.25 V to ±18 V supply. It is unity-gain stable and provides four independent amplifier channels in a single SOIC-14 package.
What applications is the OPA4227UA suitable for?
The OPA4227UA is well-suited for precision instrumentation amplifiers, medical diagnostic equipment, industrial sensor interfaces, 4-channel data acquisition front-ends, active filters, and audio processing systems. Its low noise and low offset make it a strong choice anywhere high DC accuracy and low-noise AC performance are both required.
How does the OPA4227UA compare to the OPA4228 and OPA4132?
The OPA4227UA offers lower offset voltage (25 µV) than the OPA4228 (75 µV) at the expense of a narrower bandwidth (8 MHz vs 33 MHz). The OPA4132 provides a wider GBW (8 MHz FET input) with higher input impedance but higher noise. Choose OPA4227 for DC precision, OPA4228 for wider bandwidth, and OPA4132 for high-impedance sources.
What package options are available for the OPA4227?
The OPA4227 is available in a 14-pin SOIC package (OPA4227UA) for surface-mount assembly and a 14-pin PDIP package (OPA4227PA) for through-hole designs. Both offer the same electrical performance across the –40°C to +85°C industrial temperature range.
Is the OPA4227UA RoHS compliant and what is the minimum order quantity?
Yes, the OPA4227UA is fully RoHS compliant and lead-free. The minimum order quantity (MOQ) is 1 piece, with tiered pricing available from 1 pc ($9.00) down to 153+ pcs ($1.97). Stock is available for immediate inquiry and global shipping.
