Frequently Asked Questions
What are the key electrical specifications of OPA27GU?
The OPA27GU features ultra-low input voltage noise of 3nV/√Hz at 1kHz, 1.9µV max input offset voltage, 8MHz gain-bandwidth product, 1.9V/µs slew rate, and supports supply voltages from ±4V to ±18V. Input bias current is ±15nA max.
What applications is the OPA27GU best suited for?
The OPA27GU excels in precision instrumentation, medical measurement systems, audio preamplifiers, sensor signal conditioning, and data acquisition front-ends. Its ultra-low 3nV/√Hz noise density makes it ideal for any application requiring high signal fidelity with minimal noise contribution.
How can I buy OPA27GU and what is the minimum order quantity?
OPA27GU is available for purchase starting from just 1 piece at $3.08/unit. Volume pricing is available: 50+ units at $2.73, 75+ at $2.68, 150+ at $1.35. Submit a quote request for bulk orders with fast global shipping.
What are compatible alternatives to OPA27GU?
Compatible alternatives to OPA27GU include the OPA27GP (DIP-8 version of same die), OPA37GU (unity-gain stable variant), AD797ARZ from Analog Devices (similar ultra-low noise performance). For lower cost, OPA2277 offers good precision in dual configuration.
What package and pin configuration does OPA27GU use?
OPA27GU uses the SOIC-8 (Small Outline IC, 8-pin) package with 1.27mm pitch. Pin configuration: pins 2 and 3 are inverting and non-inverting inputs, pin 4 negative supply (V-), pin 6 output, pin 7 positive supply (V+), pins 1 and 5 for offset null. RoHS compliant and lead-free.
