Key Features
- Dual JFET-input op-amp with ultra-low bias current of 0.1 nA at 25°C, ideal for high-impedance sensor interfaces
- High common-mode rejection ratio of 90 dB typ (70 dB min) for superior noise rejection in differential signal paths
- Compact 8-SOIC package with two independent op-amp channels, saving board space in dual-channel designs
Applications
The OP282GS is well-suited for high-impedance sensor signal conditioning, photodiode transimpedance amplifiers, and precision instrumentation front-ends where low input bias current is critical. Its dual-channel architecture makes it ideal for stereo audio circuits, bridge amplifiers, and differential signal processing in industrial and medical equipment. The wide supply range supports both 5 V single-supply and ±15 V dual-supply designs.

Frequently Asked Questions
What is the input bias current specification of the OP282GS and why does it matter for sensor circuits?
The OP282GS features a maximum input bias current of 0.5 µA and a typical bias current of only 0.1 nA at 25°C. This extremely low bias current is critical for photodiode amplifiers and pH sensor interfaces where source impedances can exceed 100 MΩ, preventing measurement errors caused by voltage drops across high-impedance sources.
Can the OP282GS operate reliably in industrial temperature environments beyond the standard commercial range?
The OP282GS is rated for operation across the extended industrial temperature range, maintaining its JFET input characteristics and 70 dB minimum CMRR across the full range. With 43 documented specs including temperature coefficients, designers can verify stability for applications requiring continuous operation in harsh environments over many thousands of hours.
How does the OP282GS dual-channel architecture benefit compact PCB designs compared to using two single op-amps?
By integrating 2 independent op-amp channels in a single 8-SOIC package with 8 pins, the OP282GS reduces board footprint by approximately 50% versus two SO-5 single-channel amplifiers. This consolidation also simplifies routing, reduces component count, and lowers total BOM cost while maintaining matched channel-to-channel performance of 90 dB CMRR typical.
