What are the key features of OPA4374AIDG4?
- Quad op-amp with 4 independent channels in a single 14-pin SOIC package
- 6.5 MHz gain-bandwidth product for audio and general-purpose signal amplification
- Rail-to-rail output swing maximizes dynamic range on low-voltage supplies
- Ultra-low 10 pA maximum input bias current for high-impedance sensor interfaces
- 90 dB typical CMRR for accurate differential signal amplification
- Wide supply range from 1.8 V to 5.5 V suitable for single-supply portable designs
What is OPA4374AIDG4 used for?
The OPA4374AIDG4 is suited for precision signal conditioning in data acquisition front-ends, sensor signal amplifiers, and active filter designs where low input bias current and rail-to-rail output swing are essential on 3.3 V or 5 V supplies. Its 4-channel integration reduces component count in multi-channel systems such as electrochemical sensor arrays, audio mixing stages, and industrial analog I/O modules. The 14-pin SOIC package and wide supply range make it easy to drop into both prototype and production PCBs without additional level-shifting components.

Frequently Asked Questions
How does the 10 pA input bias current of the OPA4374AIDG4 benefit high-impedance sensor interfaces?
At only 10 pA maximum bias current, the OPA4374AIDG4 draws negligible current from high-impedance sources such as pH electrodes or photodiodes above 100 MΩ source impedance, preventing measurement errors caused by voltage drops across the source resistance.
What gain-bandwidth product does the OPA4374AIDG4 provide, and how does this constrain filter design?
With a 6.5 MHz gain-bandwidth product, the OPA4374AIDG4 delivers unity-gain bandwidth for audio signals up to 6.5 MHz, or approximately 65 kHz bandwidth at a gain of 100 V/V, which suits anti-aliasing filters for audio and low-speed sensor signal chains.
Can the OPA4374AIDG4 operate from a single 3.3 V supply in a battery-powered instrument?
Yes. The OPA4374AIDG4 supports supply voltages from 1.8 V to 5.5 V, and its rail-to-rail output can swing within millivolts of both supply rails, maximizing signal dynamic range when operating from a single 3.3 V Li-ion or regulated supply.
When should a designer choose the OPA4374AIDG4 over a dual op-amp for a 4-channel instrumentation design?
Selecting the OPA4374AIDG4 consolidates 4 amplifier channels into one 14-pin SOIC, halving the IC count compared to two dual op-amps, saving approximately 30% PCB area, and simplifying decoupling with a single bypass capacitor per supply rail.
