What are the key features of OPA4130UAG4?
- Quad op-amp in a single 14-pin SOIC package reduces component count by 4x
- 1 MHz gain-bandwidth product supports audio and low-frequency signal conditioning
- FET input stage delivers ultra-low input bias current for high-impedance sensor interfaces
- Wide dual-supply operation enables rail-to-rail compatible signal chain designs
- Low offset voltage for precision measurement and instrumentation applications
What is OPA4130UAG4 used for?
The OPA4130UAG4 is ideal for precision data acquisition systems where four independent amplifier channels are needed in a compact footprint, such as multi-channel sensor front-ends and active filter banks. Its FET-input architecture makes it particularly well-suited for interfacing high-impedance transducers like pH electrodes or photodiodes. Industrial instrumentation and medical monitoring equipment also benefit from its low noise and low offset characteristics.

Frequently Asked Questions
What is the gain-bandwidth product of the OPA4130UAG4, and which signal frequencies can it amplify reliably?
The OPA4130UAG4 has a gain-bandwidth product of 1 MHz, meaning it can reliably amplify signals up to several hundred kHz at unity gain. At a closed-loop gain of 10, the usable bandwidth drops to approximately 100 kHz, which covers audio-band processing, sensor signal conditioning, and low-frequency active filter applications well within its operating envelope.
Why is the FET input stage important for high-impedance sensor designs using the OPA4130UAG4?
The FET input stage of the OPA4130UAG4 provides an extremely low input bias current, typically in the picoampere range, which minimizes voltage errors caused by source impedance. For sensors like pH electrodes or ionization detectors with source impedances exceeding 100 MΩ, a bipolar input op-amp could introduce millivolt-level offsets that a FET-input device like this avoids.
How does packaging four op-amps in the OPA4130UAG4 benefit a multi-channel analog design?
Integrating 4 op-amp channels into a single 14-pin SOIC package saves board space compared to using four discrete single-channel devices and reduces PCB routing complexity. For a 4-channel active low-pass filter design requiring matched performance, the OPA4130UAG4 provides inherently matched parameters across all 4 channels within ±0.1 mV offset tolerance.
